Not the best place to go if you own a mustang. Let’s leave it like that. Don’t know what they’re doing.

Recently purchased a 1968 Camaro SS and while it is in great condition, it needed some maintenance, repairs and upgrades. I searched around for a speed shop and decided to check out Underground Autosports. I went to their shop and had them do an inspection. Their knowledge, attention to detail and desire to do the work as if they were the owner really sold me on them. I bought the car a few weeks later for maintenance, repairs and some upgrades. I had them install a Wilwood 4-wheel disc brake conversion and a completely new braided fuel line/system. The work they did was amazing! I will be bringing it in again for some more custom work. 4 stars to Brandon and his staff!

I brought my Dodge Charger in because the original lifters failed. Brandon and the team at underground explained this was a common failure on the gen3 hemi. They estimated replacing the lifters, cam, pushrods and springs. The turn around was quick despite some surprises when the heads came off. In the end the car ended up with 100hp more and very close to the original budget. 10/10 will be returning for further work! Don’t go anywhere else!

Brandon and his team are great at what they do and have a passion for this. They're my first stop whenever I need any maintenance or work done on my Aventador.

Underground Auto did a very nice job performing the 120k mile service for my Nissan 300zx. During the process of working on it they kept me updated and were very transparent and honest with issues that arose and the steps that needed to be taken. Thank you guys very much for all the work you guys did!

Like the others said - avoid this place. I had my BMW 335is in for Cobb upgrades and they cracked the valve cover. Took a while to figure it out, but these hacks didn't own up to the damage they did. Oil all over the firewall. Huge mess. On my X5, I brought it in for some routine maintenance (before I know the valve cover was cracked) and the car was given back to me in limp mode with the dash full of alarms, but they didn't do it. Right... Cost me $2k for BMW to fix their mess. Plus, I paid for a coolant flush and BMW said there is "no way that coolant was changed in the last year." Go anywhere else and avoid the nightmare.

I never share my feedback until I’m sure that is necessary!I would give them 0 if I could!3 jobs done and each of them had extra charges!This guy’s estimate is far from accurate.After all this years in business they should be able to get you more accurate estimates with no unexpected charges.So many mistakes with the build.With my custom headers he ended up hammering my shock towers to make clearance ( custom headers, made from scratch, with extra charges - can share invoice and pictures! )Had my R8 serviced and oil leak fixed- of course there’s been extra charges.I told them to give me a favor and take a picture of everything you do but non of them has been sent.As you see I give them 2 chances alreadyIn short period of time I decided to add twin turbo to my R8 , told them to give me estimateFirst one his crew told me was $10k less from actual charges. Official estimate ended up higher but I was like, ok with all details that’s ok . But it ended up a lot higher with extra charges!My bumpers were not even reinstalled .Bumpers didn’t fit , as I requested to be able to have them back on!Instead of working on custom made exhaust he ended up trimming my exhaust tips.Talked to owner but this guy don’t care about anything then money.! He will never take any responsibility. He offered me to split extra charges and instead refund it he offered credit for next service.I’ll never go back there!!By the way, leak is still there, paid for something that wasn’t fixed .If I have to , I’ll share communication and estimates/invoicesTo give you examples how off his estimate is!Hiring those guys make sure you have extra money ready, it will cost a lot more than estimated!

Came in for front crank seal and oilpan seal replacement. Some snags came up and extra parts needed to be ordered, which was expected and is totally fine, but Brandon and Shawn didn't communicate any price increase from the initial estimate so I didn't know the final price until they called and told me the car was finished, they took over a week to do the work which was a bit excessive and the only excuse was parts take time shipping. They finally call to tell me the car is buttoned up and I go to pick it up and the alignment is off, the intake manifold was thrown on sloppily and not even tightened, the steering wheel is unclocked by about 90° and the engine timing was completely off, I'm surprised the car started and even ran at all. They tried giving me a runaround about electrical issues being the reason the car ran poorly, but I got it home and Inspected the timing with a timing light, retimed the sensor that they told me was failing, and my car ran completely fine. Scummy practices and they are nothing more than a glorified storage unit that will try to make up excuses to keep your car for unnecessary work.

How do you rate lower than one star. I was trying to find a place to install a pair of headers on my car. So it's close to home and I went there. I walked down this LOOOONG hallway and I hear DING DONG so they know someone is coming in. I'm finally inside the place now and lights are on their garage is accessible. So I wait a few minutes. NOBODY COMES. I speak loudly HELLO. Nobody comes. I waited Twenty minutes and the owners dog that was laying where I was standing gets up to get me, sniffs my shoes and lays back down. ? I turned around and walked out. ?♂️ Bye bye-bye ? you don't get my business. After searching four other places I opted for a place out in Hampshire.

These guys did a custom exhaust on my Audi. I had a vision of what I wanted it to sound like and they nailed it! High quality materials and high quality craftsmanship.
