    Glen and his Team did an incredible job on my 2025 F250. From the suspension to the custom paint work, this truck looks incredible and drives even better. The attention to detail is without a doubt the best I have seen. BlackJack Speed Shop is the only place I will take my vehicles. Thanks!!!

    Took our Tahoe in to get fender work done/trimmed for the lift that was installed. Drove it to eat, and then home. Felt something in wheel but couldn't figure it out. My wife almost got in accident next day with our 4 kids and was left stranded and found the lugnuts on front driver side to be all very loose. I contacted restaurant and there was no footage of tampering with lugnuts. Very concerened that it accidentally happened at the shop, I sent out contact emails to try and get at the bottom of it and got no response. The owner Jason called me later and said he watched video from inside the shop that the lugnuts were never touched. I will never know what happened. But him reaching back out and watching video and holding his guys to a standard is enough for me. Have done work with them often, and their work has always been positive.

    Billy at Black Jack Speed Shop took care of me and my 2022 Corvette Stingray in Red Mist metallic tint coat, I first spoke to him from anybody else at this shop and he Met and Exceeded my needs which were to get my radar detector installed on a 1LT which Is difficult thru the back of the mirror and they pulled it off with the magic of Jack who worked on my car, then they powder coated my ugly light grey factory wheels a high gloss black metallic and installed a Blue Attack air filter and finally my Corsa Extreme cat back muffler delete with AFM valves and That was my Favorite mod to the car because Now it sounds like a Real F1 Supercar !!! Thanks Glen and Gary and Jason the pickle who gave me a ride home when I dropped off my Vette to get all this work done !!! Amazing shop and I Will be coming back for more work on my car :) Mark~

    There was an aftermarket dual-exhaust system installed on my 4x4 Tundra CrewMax. The dealership wouldn't touch it and when I called BlackJack, they were more than accommodating and scheduled an appointment to take a look at it right away--even though they did not perform the original install. Turns out, it was pieced together with some modifications and welding that weren't supportive enough to hold the weight of the tailpipes. Blackjack patched it up and installed a bracket that lasted for awhile but with the weight of the exhaust (and my girlie driving... :)), it came loose again. Twice this happened and BJ was gracious enough to take my truck in and fix it each time it happened--at no cost. After realizing this wasn't going to work, I returned to BJ to order a new MagnaFlow exhaust system and install it on my truck. I was so impressed with their customer service ethic that I didn't hesitate to also have them order and install a BDS suspension lift, Fuel wheels, and 35" Toyo M/T Mud Terrain tires. They also price matched the lift and parts. Their prices are extremely competitive, their products are trusted name brands, and they stand behind their work. Alas, my truck was approaching 50K miles, so I traded up to a Jeep Wrangler Unlimited last year. I purchased the Jeep with the lift and accessories already installed by the dealer's outfitters, so I was a little uneasy not knowing much about the integrity of the install. Again, even though BJ didn't install it they willingly, and without question, were able to check the alignment and the aftermarket lift that was installed on the Jeep. They also caught that the factory lug nuts were erroneously installed on the Fuel wheels the outfitters placed on there and were stripping them due to incompatibility, so they replaced them with spline lug nuts and also rotated the tires--all at an extremely reasonable cost. I also recently got rear ended and was able to get in and out quickly for an estimate for the rear bumper with no appointment needed. Since the parts were all custom parts, I preferred to have BJ handle my claim, rather than put it in the hands of the dealer. I really appreciate the fact that I'm a female and I can walk in here (and not know a whole lot about all the inner-workings of my vehicle) and they don't try to take advantage or talk down to me because I'm not a car guru. They go above and beyond and raise the bar when it comes to valuable service. As long as I have a vehicle, I will be coming back to BlackJack for all my customization needs.

    I've had two dealings with the Blackjack in my truck-driving history. The first was in my 2014 F-150 where I had Line-X sprayed in the bed. The second was in my current F-150 where I had a deer guard, running boards, Rhino liner (they no longer do Line-X) and a trailer hitch installed. I have to say, while I didn't get back double my money, I did drive away with extremely quality work. I will pretty much leverage these guys whenever I need something done to my truck.

    They were not knowledgeable about the products they were selling and I never received a call back after asking for a quote several times.

    This is a review of the experience we had with Porsche of San Antonio…read more We dealt with Mark Rodriguez, the manager Jordan Trevino, as well as Linda at finance. Though the registration paperwork process did not initially go as smoothly as we planned for, Mark made our experience better by doing a few things right; making my a pleasant one. Mark was very responsive in communication via phone and text regarding any questions we had about the vehicle. Linda offered and explained vehicle protection plans and was able to get financing at a slightly better rate than my own banks. Though a notary had to be signed to allow an out-of-state company to register our vehicle, even though we recommended handling our own paperwork since we are well versed in registering our vehicles out-of-state. Their titling department, specifically Claudia, is quite inadequate in handling out-of-state registrations, though we provided them with specific contacts and instructions to reach out to NY DMV. Their third-party titling company requested unnecessary documentations NY DMV does not need, verified 2 months after purchase when we physically visited the DMV. Even after we found out that they lied about contacting them, they refused to submit the title document directly to the DMV. The manager, Jordan, gave us a bad attitude and kept saying "this is how it's always been done." That does NOT mean it is the best way or the correct way. Very bad experience here. Delivery was smooth; less than 3 hours from signing to drive-off. Although typical sales become much less responsive after delivery, Mark was extraordinary. After drive-off, we noticed issues regarding window tinting as well as a minor dashboard imperfection; Mark was extremely keen, took the vehicle back and retinted the window professionally at his cost, as well as replaced the dashboard trim. Though he did not need to, he even obtained a center storage compartment that I noticed was missing 2 months later. Great experience. After the amazing responses to our concerns by Mark, we are completely satisfied with the vehicle. Though Mark was great, we are however extremely dissatisfied with the registration process, as it is yet to be taken care of. We will not be purchasing another "there is no substitute" here unless the dealer takes care of this properly.

You will be the hero to your friends and family when something goes wrong with their sunroof and you can quickly say "Hang on, I know a guy..." I have a 28 year old 4Runner and the sunroof cables finally rusted up inside the channels after we moved back from D.C. 5 years ago. I have made phone calls and asked mechanics if they could fix it for the last 3 years and I get told that only a body shop will do that, body shops inevitably tell me they don't do that, try an auto glass place, and all of them say "Nope, we don't mess with sunroofs." Having a full time job, I kind of gave up on ever getting it fixed. However, I also have a mechanically-inclined brother who, bless his heart, said he could help me fix it, took it all apart one weekend and then left me with an un-drivable car for 6 weeks. My husband, in an epic Google deep dive, found Texas Auto Accessories and called Jay. I know cars and I know car guys, Jay must have an encyclopedic memory of every sunroof configuration ever produced. He takes mine apart, finds the rust, immediately tracks down one from a parts yard, I go pick it up and then he treks out to my house to install it. Who does that?? Jay does. I can't recommend him highly enough. He also installed some interior insulation I had bought while the headliner was out. He even said he'd be happy to install some new speakers in it as well when I decide I want to replace the blown one.
