AJ kept me informed along the way with what was being done to my vehicle. AJ explained every repair that was needed in detail, and was also very patient with all of my questions and concerns. My original appointment was the have the 60k service done. Timing belt, water pump, fluids, leaky hydrolic hose, etc....

My car (2000 Outback 180 k)needed more work than was originally expected. There was a lesson learned here.

I had the head gasket replaced 5 years ago by a "we can fix everything" shop. That shop took an abrasive sanding disk to smooth out the heads resulting in now having to resurface the heads which added to my invoice, also If the job would have been done correctly in the first place by the other shop, I probably wouldn't have had to replace the head gasket. The moral of this story is Take your Subaru to a qualified mechanic that knows Subarus!

A loaner car was given to me so I didn't have to reschedule any of my time.

When I went to pick my vehicle up, AJ, and the mechanic that did the repair and maintenance went over all the work that had been done, and again answered all of my questions.

Attention to detail! This is not seen to often, and this shop is all about details. Burned out Headlamp and tail light bulbs were replaced, and the sweet surprise of no charge for replacing a taillight wiring harness that had gone south. I spend a lot of my time in the woods hiking with my dog who has put layers and layers of dog drool on my windows it is now gone. The dust and dirt gone from the floors.

This shop took the care and time to make sure I am safe.

I now have a car that should serve me well for years to come. My car runs and drives beautifully. read less

They ran out of loaner cars, so they just rented one from enterprise for me. They called me right away to give me updates on my car and let me know what needed to be done out side of the 30k (which were just rear brakes) and when they went to change the transmission fluid they saw that who ever flushed it previously put the wrong fluid in. (So there has been why my car was having trouble shifting!) they walked over to the place I had the flush done and found out what it was. Then they flushed my transmission. When I got in my car to go home the front was vacuumed and it had little gifties in it. Driving it afterwords was like driving it when I bought it and I couldn't be happier.

Thanks Smart Service! read less

As a Subaru zealous state I gave Smart Service a chance and they performed Awesome-sauce.

I called to check on my car as my scheduling for the day became chaotic; they offered over-the-phone payment and would lock my keys in my car. They asked and advised that I bring a spare key pickup my car after hours.

After a long day, just wanted my car back, and Smart Service helped achieved that painlessly and left a 'welcome bag' in my car.

Cost of service was expected, however their SERVICE excelled my expectations. read less

Smart did the job for much cheaper than what the dealership quoted me and to date (which has now been years later), the brakes are still in great working condition.

The second time that I used Smart was when I had one of the locks on my door suddenly stop working. Dealership told me it would be $90 just to assess what the problem was. Smart diagnosed free of charge and also fixed the problem for cheaper than $90.

And most recently I used Smart for a second opinion on my front axles. Again had dealership tell me that my front axles needed to be replaced. However, as I hadn't been noticing any issues, I took my car to Smart for a second opinion. Smart inspected free of charge and let me know that the axles are currently operating fine and not in need of replacement at this time. I appreciate that level of honesty and not telling me I needed a $1,400+ repair job when I really didn't.

Great service and I highly would recommend Smart! read less

They did a great job on my Subaru maintenance and I felt the prices were really fair. The service specialist patiently answered all my questions and went through all the work they completed. (I am extremely anal about going through the maintenance check after getting burned multiple times at the dealer - Smart Service was totally tolerant of this and walked me through everything).

He also took meticulous notes on my car and any 'watch' items that may need to be worked in the future. He did NOT try to upsell me on any additional services (pet peeve) thankfully and didn't urge me to replace things that I could get more miles out of.

You can tell they take pride in the work they do. This is a smaller shop but it makes for a more personal experience and you don't get handed off to slick-talking salesman after slick-talking salesman.

After spending thousands of dollars on a new engine several weeks ago, you can imagine the frustration I was feeling when my car began having trouble starting, and the check engine light started coming on. I took it to the same company, only here in Shoreline. It turned out to be a sensor, but was going to cost around $250. I'll admit it--I cried. I can think of a million things I'd rather spend my money on than this [email protected]$# car, and I just felt frustrated!! I could tell the two men working had NO idea what to do with my emotions, and I apologized and explained how much I had just spent at their other store. Well, they had to order the part, so I went today to have it put in. When I went to pay, they graciously said NO CHARGE. Say what?!? And so I cried some more. Haha. But seriously--these people have heart, and they do an excellent job. I don't know if they realize how thankful I am, but wow, my heart is full. read less

I needed a trustworthy, honest, and friendly mechanic that specialized in Subarus, and as a woman, sometimes it can be intimidating dealing with car "stuff." I have always felt comfortable with these guys, and you can truly rest assured with them.
Recently, I had my Subaru stolen from the Alderwood Mall. After it was recovered in Seattle, and dealing with a head-ache of towing companies, police departments, etc and it finally being found in Seattle, it was towed to Smart Service. Amidst a very stressful time, as they evaluated the car, and after I found drug syringes and paraphernalia (thanks thieves and Seattle PD for not processing), Smart Service was gracious, timely, and accommodating to me and my insurance company. They let me use one of their loaner cards for a few days and facilitated towing my car up to an off-site detailing shop. It was my car's "home" during that time. Thank you Smart Service for your excellent customer service!! I highly recommend Smart Service, and have recommended them to many other Subaru owners (including my sister and father). read less

I've always gone to the dealership, but have heard a lot of great reports about Smart Service, so I gave them a chance with a major service, and a unique hood latch issue.
1) The major service was much less than the dealership, and I was quoted what I thought would be a fair price for the hood latch repair.
2) The results - great communication, a free rental car (because it was a major service that took all day), and most importantly they informed me that they ran the my Tribeca's vin number and found out that there was a recall for the hood latch. As a bonus - they didn't even charge me for the initial work done for the hood inspection, and recommended I take it to the dealership for a free repair. In other words, - they are honest, saved me money and went the extra step to earn my loyalty.
I'm a convert - no more high priced dealership repairs... read less

I own a 2014 Subaru automatic Impreza and noticed a whining noise in the cabin whenever I hit ~55mph. Every time I took my vehicle to the dealership for maintenance (30k major, and 45k minor service) they didn't note anything about the noise even when I had mentioned it to them prior to the service so I assumed it was nothing and decided against looking into it further.
For my 60K major service, my friends recommended me to choose Smart Service. I decided to bring up the noise issue with them, thinking maybe they can figure it out and within hours they paused the 60k service to notify me about the noise. It turned out that the bearings inside my CVT were failing and that was the reason for the noise. Luckily my vehicle was barely under warranty and got the entire transmission replaced by the dealer. (Dealer quoted me $9,200 to replace if warranty was expired) After I got my vehicle back I then took it back to Smart Service to have them perform the 60k service. The 60k service went well and Gallagher sent me update texts throughout which were awesome. This level of attention and care is the reason why I will only bring my Subaru to Smart Service here on out.

TL;DR: If you love and care for your Subaru as much as I do then this is the team to trust. They're honest, knowledgeable, friendly people. Huge thank you again to Charlie, and Gallagher and the rest of the Smart Service team! read less

I recently had my 1998 Outback's 210k mile service and timing belt done (Subarus last a long time if taken care of, people!) and they did it for a pretty reasonable price, along with a lot of other work (new water pump, steering rack seals, etc).

They also did the timing belt service on my wife's 2000 Outback with quick turnaround and quality labor.

The only ding from 5 stars is that they contract with Enterprise Rent-a-Car for service loaners, and the cars are really bottom end (Kia Rio with absolutely no power). But you do get free service loaners - most independent shops don't even have 'em. I'd rate Smart Service 4.5 stars if I could. read less

Every time I have taken my car in, they've been spot-on with the cost estimate, which comes in consistently at around 30-40% less than the dealership even with the dealership coupons that get sent my way every couple of months. And they are all Subaru Master Mechanics, so I know I'm getting the best for my car.

A couple of years ago, they mentioned that my rotors only had about one more resurface left in them, and showed me how to check. They warned me that the OEM Brembo rotors cost a fortune (which I verified with the dealership - holy thievery, Batman!), but since I had some advance warning, I was able to find and procure an aftermarket set of rotors that performs at least as well as the Brembo units for significantly less than the OEM cost (which they installed for me once my rotors finally needed replacing).

While I was waiting in line to pay, the lady in front of me ended up getting some free service/advice on something (I don't recall exactly what it was) that was a 5-minute fix. This is the kind of place I feel like I can refer my grandma to, and not worry that she is going to get sold some service that she doesn't need.

Knowing that I have a reputable, friendly place to take my car is enough of a reason to consider a Subaru before any other make of car the next time I'm in the market. How many auto repair shops can you honestly say that about? read less

I trust them to provide thorough, careful service and repairs, to keep my cars reliable (I keep my cars for a long time) and to charge a fair price. As a single woman for most of these years who doesn't know a lot about cars, it was especially important to me to have mechanics I could trust, who explained things well and who didn't try to talk down to me or take advantage of my relative ignorance. Mike and everyone I've interacted with at Smart Service are always professional, friendly, and communicative. They are also good about being clear about when I can wait to take care of an issue vs. something that is more urgent. In 20 years they've never messed anything up or broken anything and I always feel I can count on my car to be reliable and running well after service or repair. They usually leave it sparkling clean too. I highly recommend that you take your Subaru to the professional, fair, and friendly folks at Smart Service (and I think they're servicing Hondas and Toyotas now too)! read less

Our subaru broke down Thursday night, and we had it towed to Smart Service around midnight. Friday they called and said that, if needed, they could come in over the weekend to fix our car. Really??? We didn't need it by Monday, so we said no, thanks. Anyway, they did a service check on our car and found a ton of things wrong with it, and gave me a cost breakdown and gave me the option of picking what I wanted to fix, and gave me advice on what was really necessary. Me being a sceptic, I had my fiance call his mechanic friend in NY and he agreed with the diagnoses and suggested repairs. It ended up being really pricey, but that's because they also fixed a rear main seal oil leak. They finished our car yesterday (Monday) so we only went the weekend without transportation, and they gave us a list of parts and service needed so that we could work on the rest by ourselves. It was really more than we expected, but exactly what we needed to save money by doing our own minor repairs. They also sell Subaru auto parts there, and are nextdoor to a Schucks.

I was in for 90k mile maintenance. First, making an appointment over the phone was super easy and I got a loaner car reserved for the day while my car was in the shop. Dropping the car off in the morning was speedy and they had me in a loaner car and on my way to work in about 15 mins. They send a detailed service report and let you know of any additional maintenance they would recommend right away and let you know things that you can wait on. The price for the 90k service was great compared to a Subaru dealership. Lastly, they wipe down the car and do a quick vacuum. I left with a cleaner car then when I arrived! Hands down a quality experience with very friendly people to work with. I will be back in a few months for my next oil change. Thanks Smart for the great customer service! read less
