    What the part look like.

    If I could give negative stars I would. Went to get a simple cart welded for my car so I can put it on a tow truck. I showed the owner the picture of how it looked and how it needed to weld it, he welded it completely wrong. I told him and he didn't even care or apologize about it and still wanted me to pay. Mind you I am even mad. What pissed me off is him saying I don't work with your kind after he took my money and delayed my process of getting my car moved. I will be reporting this shop to the BBB and take whatever actions that I need to. I went in super respectful too didn't even complain about him welding it wrong. If I acted like "my kind" I would've put my hands on him. But I am an active duty member and I respect my elders. I will be reporting that.

    I brought my 2020 Mustang GT to have an X Pipe installed. I was quoted 150 $ for installation. These were the results. I was told it would be another 160$ to fix the mess the had made. I decided to bring it to a different shop where they fixed this botched experiment. Be careful.

    Bad welds. Leaking exhaust

    Went here earlier this week for a muffler delete. They did that exactly and everything was good. Minus poor positioning on the rear tail pipe now hanging down. After driving back home I noticed a loud rattling sound coming from under the vehicle, so I had called the shop and I brought the vehicle back. Looks like they forgot to weld in another hangar which caused the pipe to rattle on the sub frame. Fast forward to the next day, I start my car and notice a large moisture leak under my vehicle coming from the new piping they installed.... Looks like they never fully welded and sealed the pipe. Not just in the front but also in the back. ( see pictures) I took my car to another muffler shop to get the job done correctly and they pointed out a lot of things that were incorrectly done. BE CAREFUL GOING HERE

    I just went to this shop to fix my car exhaust and a mechanic cut the exhaust, he couldn't do it and even damaged my car. Bad service

    1.Catback installation  2. awe valve simulators on actuators  3. Modify stock exhaust to adjust fitment for new exhaust

    Went in for an install of an aftermarket exhaust catback. This was a process of an install because I had to buy a separate piece of hardware so a check engine light wouldn't appear on my dashboard when the new catback would be installed. At first I was kind of disappointed because they thought they had to cut the catalytic converter and they don't do that there but after more research, Luis and I found out we had to modify the stock exhaust a little bit since the catback had some fitment issues. The company also said it was a direct bolt on, which it was. Luis modified the stock exhaust by cutting some pipe to make it work and boom it did! They then installed some valve simulator plates on my actuators so my check engine light wouldn't pop up. It worked fine! Everything went smooth besides the fitment The owner is a honest man and their service is good! Thanks again Luis. ¡Muchas gracias Luis! Also, I was getting quotes for the catback installation for around $400.00 from other shops. With this shop I paid close to $170.00 WHAT A DIFFERENCE. I'd recommend them to anyone looking for honesty and good pricing.

Their prices are the most fair in the area, but the quality, the skill, the knowledge that were provided was TOP NOTCH. Very honest and knows alot about cars. They deserve your business and referrals. I called them and they were able to squeeze us in after I told him we had an urgent case and needed their help. He found more issues that other shops probably wouldnt have caught. Auto scientists with MAD SKILLS. Arnold educated and guided me and we were able to make the best and right decision on the vehicle.

If you need a pre-purchase inspection or any auto repair, whether it be european, american, japanese made, etc, and EVs, take your car here and don't think twice. We reached out to Arnold for a pre-purchase inspection. While six other places quoted us $250-$350 for a "comprehensive" inspection, we paid Arnold $100, which was a STEAL for what he did, even more than what the others promised. He spent at least two hours thoroughly checking the vehicle, test driving it and walking us through every detail so we truly understood its condition. We were looking at buying an Audi Q4 e-tron that had a damage report. A reputable dealership told us it was "minor" and offered to take it to the mechanic for our peace of mind. After browsing Yelp and reading the amazing reviews, we decided to come here instead and I'm so glad we did. I had already done my due diligence and familiarized myself with the vehicle and potential issues. I asked Arnold very specific, technical questions that I already knew the answers to. He answered every single one with clarity and confidence and everything I was expecting to hear. My husband stayed the entire time, and Arnold patiently explained everything while inspecting the car. You can tell he was that kid that made the auto shop his playground growing up. He's passionate, meticulous, and GENUINELY cares. What impressed me most is that Arnold will never pressure you. He won't tell you "don't buy it," but he will clearly explain what could go wrong and what it might cost to fix. When I pressed him for his honest opinion, he said he personally wouldn't buy it at the listed price but if we negotiated it lower, then it might be worth considering. That level of honesty is RARE. They are your small local auto shop but I would choose them over any flashy, grandiose service center any day. Their integrity and transparency make them stand out. Thank you so much, Arnold and your dad, for the amazing service. We ended up just buying a Tesla!

I walked in and they immediately greeted me, helped whoever was in line, and then came out with me to look at my tires. The gentleman who helped me looked at them and then explained that what I needed was new tires not a patch. My tires were so worn that he did not recommend me driving a long ways on them. I asked what the cost would be and he gave me three different quotes so that I could choose the one that best suited me. I recently had body work done on my car and was saddened when the gentleman let me know that a tire alignment was skipped. They replaced my tires within 2 hours (they drove and picked up my tires from another location) and did the tire alignment and they also made sure I was comfortable the whole time. I have a lot of appreciation for this place and you should too. I've been driving on the new tires for two weeks and my life is changed. Highly recommend for tires, alignments, tune ups, and everything in between. The mechanics also interact a lot with customers and seem pretty happy here (that's a good sign).
