National City & San Diego, CA Auto Repair Shop Services

“Brought my Mercedes in for an inspection & they brought a few items to my attention & also replaced the hydraulic pump for the convertible. Excellent work.”

“5 stars!”

“5 stars!”

“I friend recommended this place to me after I mentioned needing some work done on my son's SUV and I'm so glad to have finally found a solid auto repair shop!

I was really in need of finding an honest and fair shop, because unfortunately that is a bit hard to come across these days. I had taken my cars to other places in the past but I most always left feeling that I had overpaid and possibly for repairs that weren't quite necessary.

My experience with the owner Tim and his crew proved to be spectacular!

The SUV I took in had one major problem that was identified right away by Tim and he quickly got me in. I left the SUV with him and a couple of hours later he called me to discuss other findings and give me some options.

I work in the Kearny Mesa area so I was able to come down a take a look with him. In a nutshell, there were other things that needed attention and instead of Tim just pressuring me to spend more money, he took the time to break down, the actual severity of the other repairs and sort of gave me a plan of action that I could follow when I could afford to spend money on them.

That's just something special that you don't find in many auto repair shops and it blew me away.

Since then, he takes care of all my vehicles and I when the work is done, I never leave with a bad taste in my mouth. Instead, I leave feeling confident that I've been taken great care of and my problems have been solved.

A big thanks to Tim and the crew at Underground Autowerks!”

“I took in my 2019 Audi R8 v10 spyder and my 2019 Mercedes S65 and they took really good care of me and my cars. What a great shop. I’m very happy”

“Stopped by this shop while on a small getaway due to my car having a issue that it was shaking. Tim helped me out and informed me that my car was low on oil and needed an oil change. I was relived that it was such a small fix because I had to drive back to LA the next day. Tim I want to thank you for being honest because you could have told me it was something much bigger and I would’ve believed you. I was gone within 30 minutes. Definitely stop by this place if you need any work sone”

“Got a few performance upgrades for my BMW. Great work, on time, everything feels great on the car now. THANKS!”

“Amazing experience from start to finish! Tim listened to my concerns, gave an honest diagnosis and took the time to explain everything in great detail. This was the third shop I brought my car to for the same issue and Underground came in about $600 less than the other quotes I had received. This will be the only shop I deal with moving forward. A true 5 star establishment.”

“These guys took care of me at a really reasonable rate. Felt like they really cared and wanted to get me back up and running, not just get me back out the door. Will definitely be back if I need any further work.”

“I can always count on these guys to be upfront and provide a great service at a fair price. I will never take my car anywhere else!”
