On time and super helpful. Thanks Grzegorz!

Grzegorz is very knowledgeable and professional and experienced as a car mechanic. I trust him with my VW and appreciate that he doesn't perform work if it's not needed. Highly recommend him

Grzegorz was very professional. He wasn't able to get my battery going the first time, so went home to get some extra equipment and make it to another appointment before coming back a couple of hours later to try again. I appreciated that he didn't just say "too bad, I can't help you". He was able to get the car started enough to open the boot and replace the battery when he came back, saving me a tow to the dealer. I would hire Grzegorz again.

Grzegorz has been helping me get my 2004 Saab in shape again. I just bought it, and it needed some love to be in tiptop shape, and Grzegorz has been awesome in helping me do just that. It's running wonderfully, and I'll continue to have Grzegorz work on the car throughout its life which I hope is long. Thanks Grzegorz for all your work, and helping me understand what is going on with my new baby!

I really enjoyed talking with Grzegorz and learning a bit about how my car was working (and not working). What he did brilliantly was say "I don't understand you my english is not very good, what I understand by the word you are saying is this..." - that is awesome communication from someone communicated in a language that is not their native tongue. Love it! Thanks Grzegorz for being patient with my lack of knowledge of cars as you taught me, and for helping me understand what you didn't understand from what I was saying. Excellent service!

Grzegorz put extra effort into diagnosing my Mini's problem with overheating. He tested the car more thoroughly than many shops I've taken it to and for half the price. Very professional, thorough, on time (early!) and great followup. Thanks, Grzegorz! I'll be requesting your services again.

Grzegorz is awesome. He's very thorough and has helped get my car back on the road. He explained everything and gave great suggestions on how to keep my car running well.

Grzegorz was quick at pin pointing the problem with my car and fixing it. He was also helpful in letting me know what caused the problem and what to look out for if my problem should occur again. Overall he was very helpful.

Grzegorz was very knowledgeable about what maintenance was needed and helped explain to me the indicators I'd see for when certain parts would actually need replacement. The opposite of a pointless upsell, and made me feel comfortable with the safety of my vehicle.

Grzegorz was great. The previous mechanic who worked on my car was unable to solve my car's issues and said he needed to go through an extensive + costly trial and error approach to fix my car. In comes Grzegorz- he was able to diagnose the issue in 5 minutes and had my car running immediately.

Grzegorz did an excellent job. Before him arriving I thought I needed a brake master cylinder. But, when he got here is checked the whole braking system and recommended changing the brake pads since the master cylinder was working well. Thanks again Grzegorz.

Greg is my go-to YourMechanic guy. He's very detail oriented and gets the job done much better than other YourMechanic-mechanic. He knows his stuff and even do extended diagnosis of my other questions of the car. Dan

Grzegozs is a first-rate mechanic and finished the break job and assessment of the vehicle ahead of schedule. I would also like to commend is personal culture of safety. Not only did he work efficiently, he worked safely. Great guy!

on November 17

Very knowledgeable, professional mechanic! He was accommodating when I had to reschedule my appointment and was an expert at replacing my battery. Highly recommend - A++ service :)

on November 18

Grzegorz arrived on time and ready to work. He finished the work in the estimated time and made sure he did it correctly. He even ran out to the autopart store to get the correct part that was missing.



Honda Civic
on June 18

Grzegorz is a trust worthy mechanic, He installed a new Engine/drive belt plus a water pump on my 2005 Honda Civic. He answered all the questions that I had for him, he also gave me some pointers on car parts and how to fix things for my self . I recommend him on fixing your car as well.



Kia Spectra
on November 11

Grzegorzs is the best mechanic in the Bay Area hands down! He went the extra mile (pun intended) taking care of my Kia spectra to make sure everything was working properly. I never felt taken advantage of or price gouged which unfortunately can happen with a lot of mechanics. Great work!

on November 09

Grzegorzs was friendly, informative and great. Highly recommend him and would definitely ask him again to fix something on my car. Very happy with my experience. And so convenient. Coming to my office!

on November 18

My regular shop mechanic refused to fix my door actuator (because it's a pain to tear down the door and put it all back together again), so I hired Grezegorz. The door works great, my locks operate again, and the car was clean and in good working order. I'm confident in his skill. I would hire him again. Very happy.

Thought it was a belt issue due to the squeaking sounds coming from the car. First thing he did was check the belts and immediately said the belts were still in great condition and didn't need to be replaced. I like how he was honest and didn't try and take advantage of me and change them anyways. Then went and diagnosed and told me what the problem was. Gave me a quote to fix the actual issue and didn't pressure me at all to make an appointment with him immediately. He also managed to stop the squeaking noise in the meantime which is awesome.

on November 04

Gregory's was punctual, very friendly and extremely knowledgeable. Not only did he diagnose my issue, he gave me a heads up in a few other things to keep an eye on.

on November 01

He is the best mechanic I have ever met in the bay area. I asked for a general inspection on an used car I just bought. He was so kind to point out what problem my car have. Now I know which parts needs to be replaced.

on October 30

My initial inspection was quick and easy. Grzegorzs is thorough,professional, and quick. He explained all the findings with my car. I have re-booked him for a recommended repair.

on May 21

Greg was very flexible and offered me several options for the mobile service. I opted to take my car to the shop instead of using the mobile service and was very pleased with his experience, professionalism and knowledge. I would go out of my way to have him service my car again.

on April 20

My experience from implementation to completion was flawless. Gregory contacted me the day before my appointment to confirm my appointment. Due to the nature of my repair and the location I am in Gegory asked if it were okay to do the job at his location. Knowing how difficult it is to r&r the front assembly for cv axel joint replacement I did not see a problem with this. In fact I was wondering how it was going to happen. Anywho, Gregory dropped me off and picked me back up when the repair was completed.He even gave me a few items that may need repair that my other mechanic missed. I will most definitely look him up for future repairs or maintenance.

On time and communicated the issues with work to be done. Completed the repairs quickly, showed me the replaced parts, and I was back on the road. Grzegorz is very professional and knowledgeable and I would request his services again.
