Complete Auto Works

After over 20 years in the trade as an auto mechanic myself I recently changed careers. Now left without a facility to work on my own vehicles I was faced with the dilemma of finding someone trustworthy to work on my vehicles. I looked no further than Mark at Complete Auto Works. Honest, trustworthy, fair. I highly recommend his service, you will not be disappointed.

Mark is the best! he’s honest, he’s fair and has the best customer service of any automotive shop I’ve ever been to. Oh? did I mention he’s also a great mechanic. He’s been caring for my 2003 BMW for the past 4 years. Since I live in Fairfield, it’s not very convenient for me to get to his shop in Concord. He always takes that into consideration and works diligently to get me in and out. Don’t bother looking for a deal because Mark is the real deal. Read the other reviews and make an appointment.

The best! No need to go anywhere else. Read the other reviews, pick up your phone and make an appointment.

I have a 2002 Toyota 4 runner. At first i took it in because the ac compressor needed to be worked on. Mark called me later that day to tell me it needed the ac compressor and about another $ 1200 worth of work due to the previous owner not having the 50,000 mile work done by the dealer. Mark gave me a estimate of X amount of money and told me he could have it done in 3 days and it was done right when he said. When i went to have the work done he did much more than what he had put in the quote but stuck to his original price. He put top notch parts in and some dealer parts. He did some brake work and a couple other things for which he did not charge me. My neighbor has been going to mark for many many years and told me i could trust mark. After having this work done i will never go any where else and always trust marks word. He does not try to get over on you and will always give you the honest truth.
Thanks again Mark for all the work and the great service.

BEST AUTO SHOP EVER! I have a 2000 VW Beetle (notorious for issues) and the previous shop I had brought my car to changed my starter and re-​coded my key. After leaving said shop my car wouldn’t shift. I brought it to Mark and within 30 minutes he had the problem fixed and I didn’t even need a part! The previous mechanic didn’t clear the codes in my central computer and this was causing the issue. Along with the awesome job on my car, Mark and his staff were extremely helpful and cheerful. The previous mechanic had also torn some of the plastic cover under my car while trying to complete their repairs, Mark’s staff zip tied it to the bumper and made sure that it was in the correct position, so it wouldn’t get caught on anything and rip more. So Sweet! They now have a customer for life!

Dependable, honest and if it isn’t right, he stands behind his work.

There is not much that I can add to all the prior reviews but I will:
As a senior manager for a 2B a year medical products company I drive Customer service everyday, the customer comes first, no customer no business. Mark gets that he treats all his customers with respect and listens to their problems. I came from concord Dodge Fiat etc with smoke coming out of my ears. Mark stopped what he was doing and worked with me to find a solution. Mark has worked on other cars for me relentlessly under some very strange conditions. Mark gets a 10 across the board. Great customer service always happy and has the desire to get you back on the road with the least amount of hassle possible. All the big box dealers should take a page out of Marks book, they might not have so many pissed off customers. Great job Mark
Thank you

Not much else to say but Mark is a guy that is there to help you, not rip you off. His prices are incredibly reasonable, his service is impeccable, and he is always there to answer the phone and speak with the customer about his vehicle. Great honest shop that does great honest work.

Posted before. in 2010, but want to update… Mark always does great work… Never an upsell like all the other places you go to… Wife’s car needed breaks which I knew… Also need Shocks and Struts. Mark said do the breaks now… shocks, struts can wait, but do them before you replace the tires in six months or so… Had i gone to the dealer/​wheel works/​big o… whatever, they would have tried to rope me in a complete package… breaks, tires struts, shocks, alignment etc for a «great one time deal».No thanks. Mark is as honest as it gets. He does not need to upsell/​oversell… His shop is small and packed all the time

Honestly, they don’t get any better than Mark.
I have an aversion to getting screwed by mechanics and unfortunately have more times than I care to admit. Enter a guy (Mark — the owner) who treats you with respect whether you’re a guy or girl, whether you’re car savvy or clueless. I’ve had Mark as my mechanic for over three years and during that time he’s worked on three of my cars. In every case I have been extremely pleased with his prices (I’m a miser) and with the quality of the work his shop does.
I recently had a bad experience with a car, that at times they can be lemons. I had a warning light show up on my dash. Mark told me from his experience what he thought it could be but also told me that it could involve more work depending on if the initial troubleshooting didn’t resolve the issue. It didn’t but he and his team stayed with the issue and gave me updates along the way so that I could decide whether to keep moving forward or cut my losses. I so much appreciate that approach over the one where you show up to pick up your car and get surprised that they just did $ 1,000 worth of work with minimal explanation.
Only downside is, he’s busy but in my book that means others see the value of what he does and appreciate it so I can live with working around his schedule even if it means dropping the car off for the day or booking 4 weeks in advance.
Trust me; you won’t go wrong with Mark. He’ll do everything he can to make it right.

Mark is honest and straightforward. Had to have my radiator replaced and it ended up costing considerably less than I thought.

This guy is the guy you’ve been looking for.

Best mechanic around!!! He is very fair and honest. I had a list of things that needed to be done on my 2000 Nissan Maxima. He let me know what my opinion were and what I should handle first and what could be taking care of later! I must say he got my car to pass smog twice when no one else could it runs like a new car! 5 star service

In a world, where you can’t trust taking your car anywhere for maintenance out of fear of being screwed over, there is a light.
After reading nothing but positive reviews, and then talking to Mark over the phone, it is was obvious that this was the place we’ve been looking for. Drove the car in Wednesday morning, and when I walked into the office, Mark knew me by name just by seeing me drive by in the car. We talked about what I thought the problem was, what could possibly be causing it, and how much it could possibly run.
A few hours later I get the call from Mark, informing me that they are replacing the coolant tank and gave me an updated price which came out to just a tad cheaper then what we originally thought. Sweetness. I walked over, since it’s a bout a 30 minute walk. The car wasn’t ready yet, but Mark apologized, and they set to get to work on finishing it quickly.
Do yourself a favor and avoid being overpriced and possibly being had. Come here for an honest auto maintenance job.

Mark was great. I took my car here for a major tune up and needed a lot of work. Mark was nice and really helpful. He worked with me when I couldn’t get all the tune up done at once, he made arrangements on what really needed to be done first and knocked off a couple of bucks here and there to fit it into my budget. I did my complete tune up in two trips and my car has been running great. I’d definitely come back here for any car problems in the future.

I’ve taken my car in 3 x for regular maintenance. I just know I wont go anywhere else — i trust Mark because he is honest, knowledgeable, thorough and truthful. Im happy I found this place!

There is something to say about reviewing a company that has all 5 star reviews. My entire family have used Mark for their auto repairs for over 10 years now. The last incident is just typical of Mark, he was working on my wife’s Jaguar because it stopped on the freeway THREE TIMES! I took it to him after the first time and he said he couldnt figure it out, I took it to him after the second time and he looked up all of the possibilities and offered to send a part off for a very expensive repair but he didnt think it was for sure the problem. I took it to him after the third time and he did MORE FIXING on a bunch of little stuff he said and I took it for a 3 ½ hour test drive with his testing equipment attached to the car and it didnt stop. It baffled us, but I took his meter back and asked how much, and he said he would charge for it. I couldnt believe it, he has put in a lot of time on it and still no charge? I couldnt help but let others know how honest and fair he is.
Another time I took my daughter took her car in because it was having difficulty starting and he immediately diagnosed it as a loose battery cable, he tightened it and he didnt charge her to do it.
What a great guy!
I have more stories about him too

Mark the owner is as honest, knowledgeable, thorough as you can find. I have been to his shop for the past 7 years. He came to the house one time to save me towing fee.
You talk about good, honest mechanics, Mark’s the man! I highly recommend him.
Oh, and he sends Christmas cards!!!

Came in and asked if they allowed walk-​ins due to the fact that I wanted to do a pre-​purchase inspection before buying a used car from a near by dealership. They were booked up, but said they might be able to do it in an hour or two. The owner knew we only had a limited amount of time until the dealer called us wondering where we were, so he took time out of his busy day to look at it, while also calling upon other two mechanics who worked for him to look at it as well. They drove it around, precisely looked at the engine, underneath the car, and did about 20 min inspection. The owner did not charge me as well which was wonderful as well. They were very helpful, welcoming, truthful, and nice overall. Will be back to do business with them again! (:

Mark and Complete Auto Works has taken care of my car for years — honest about what really needed to be fixed, fairly priced, and always did the best he could with his busy schedule. If I could take three things with me when I got a new job, my mechanic would have been one of them. Now I’m too far away and I’m on Unilocal looking for someone to change my oil!
