    1969 Camaro SS
    alex n.

    I went here strictly on Yelp reviews and boy am I glad I did. This father and son team did an amazing job on my Camaro. Took it in for a tune and dyno run. They fixed a vaccum leak and adjusted the timing to a T. The motor runs like a Rolex now. The thing does not miss a beat. It's so hard to find a good mechanic that knows what they are doing. Needless to say I will be bringing it back after I get some exhaust work done. Their rates are awesome and very honest too. Thank you guys for an amazing job!!! My motor is finally happy!!! My new go to place for service on my Camaro.

    I spent 7 years building my 1954 Cadillac Convertible. I installed a brand new LS3 crate engine and it ran great from the first start. Then I took it to DeLeon. What a difference. They took great care of my car, were clearly knowledgeable about my engine and controller, and they got great results. I highly recommend DeLeon.

    I brought several of my cars to DeLeon and always had great experiences. They always give me a great solid advice.

    Brought my 72 c10 in because it wasn't running right. Victor has the most experience with classic cars and I'll recommend him to anyone

    I took a classic Corvette that I love to Victor, after I scouted out a bunch of other shops and looked at what they do.

They were able to squeeze me in, and match the best price I had found to earn my business. Once I arrived the experience was amazing and smooth from beginning to end. The owner Eli chopped it up with me for a while, then let me chill in the back since I was not from the area and it was late. Talk about great hospitality and top notch service. On top of A1 customer service. The attention to detail and quality was also on par. Look at the pics for yourself. I will be a returning customer 100% !

You can tell they take a lot of pride in what they do. Everything was done with great attention to detail. Even though my car is a little dirty in this photo, it's still incredibly shiny, and you can clearly see the reflections of the surroundings on the paint. That alone speaks volumes about the finish. Eli was super easy to work with, communicative throughout the process, and made sure everything was done right. I'll definitely be bringing my car back to SV Customs for future projects and wouldn't hesitate to recommend them to anyone looking for top-tier work.

    High-level summary:…read more Customer service (patience, friendliness) - 5/5 Technical knowledge - 5/5 Transparency - 5/5 Review: Given my previous experience with torn bushings at 57,000 miles and consistent premature wear-and-tear on my tires - replaced every 20,000 miles or so, partially due to my lowered car with a staggered wheel arrangement and poor alignment - over the lifetime of my 2018 Tesla Model 3 Performance, I wanted to take a preemptive approach at 125,000 miles in improving and preserving the functional performance by doing a suspension refresh. After doing extensive research on MPP suspension upgrades, I reached out to TDW Auto and sent a summary of my desired scope of work, my budget, and a request for feedback on whether I had the correct approach in addressing my concerns. From Will's first response, we had seamless back-and-forth conversations over E-mail and text to clarify the current setup of my car, highlight my major concerns, address these concerns with the proper MPP upgrades, and align on my budget, must-haves, and nice-to-haves. There was never once an upsell; only cautionary words of unnecessary upgrades for my use case, which is really just the daily work commute in a lowered setup for personal aesthetic purposes. My original request included MPP front upper control arms and rear traction arms with my Unplugged Performance lowering springs, along with swapping out the front lowering control arms and rear camber arms. However, Will explained that the FUCAs and traction arms served no improved performance for commuting, and that the existing springs were more of a budget-friendly fit that compromised on long-term performance due to its reliance on Tesla stock dampers. Instead, he recommended swapping out the springs for MPP coilovers, and replacing the toe arms in conjunction with the camber arms to improve upon long-term lowered car hardware wear-and-tear. I followed up with Will after our virtual exchanges to get his opinions in person. He took me out for a test ride with me in the passenger seat, immediately identifying that my dampers were squeaking noticeably and that hard cornering at highway speeds felt bumpier than it should. Additionally, he patiently answered all my technical questions over the hour I was there, and adjusted the quotation when I made the final decisions on the suspension refresh. Will was completely transparent about pricing: he categorized the costs by the "front" and "rear," clearly highlighting the number of hours required to replace the front control arms, coilovers, and rear camber and toe arms. Alignment was included in the coilover work as well as solid front lower control arm pressing. He was even able to slot me in his 2-3 weeks' booked schedule on short notice because I wanted to complete the suspension refresh before making a drive to Canada. I picked up my car today after leaving my car overnight, and am extremely satisfied with my decision and results. Special shoutout to Mike, who I believe is the other co-founder and technician who stayed late just to work on my car to meet my schedule!

    If you're looking for an enthusiast owned shop that is OCD about alignments, this place is it. I…read morewas trying to avoid a situation with a national retail shop that look at default settings in their system and align without questioning why or what the customer would like to achieve. I have a Tesla Model Y Performance with Mountain Pass Performance (MPP) comfort coilovers and rear camber arms. I looked all over the South Bay for an alignment shop that knows Teslas well and found the right shop. They will walk you through what you're looking to achieve (in this case for my rear wheels, they recommended less than -1 degree camber for daily driving) vs. the insane -3 degree I had before / good go track, pointless for my everyday highway driver to the office and back. OCD about details like setting tire pressures up correctly, not blindly following shop manuals, and a test drive to make sure all is in spec before delivering back the car. Owner Will is very responsive and being a car guy won't give you the run around but knows his stuff with his technician and co-founder. From setting up race spec Teslas to doing a basic daily driver friendly alignment (what I needed to stop chewing through my rear tires) this shop has you covered. I even got my date wrong and instead of turning me away, got me in at the end of the day as I was already on my way. Pricing was very fair and will take my BMW M3 and Ferrari 360 in the future to the same shop. 5 star experienced can't recommend enough.
