    John custom welded a frame to hold my 100gal water tank to assist with my gravity feed system.

    My go to mechanic for everything. From an oil change to custom work to your needs, John at SJ Customs can get it done! His prices are very fair and competitive with quality work. I came to John with my new work van and needed help setting up some detailing equipment. He helped custom designed and fabricated many parts to my build. I absolutely love my van, and am amazed at his craftsmanship and ingenuity.

    I came to John for my Mercedes Benz Headlight Swap. He is very detail orientated and took the time to make sure that the bumper is removed correctly in order for the headlight to be removed safely. He is a very pleasant and honest guy. I would recommend John for any auto customization you need!

    John at SJ Customs installed a freshened up LQ4 engine, 4l80e transmission, and new posi rear end into my Chevelle.

    John at SJ Customs did an outstanding job doing an LS swap on my '72 Chevelle. From the initial planning phase and ordering of parts, through the installation and fine tuning, John was great at taking the time to answer questions and keeping me informed. The job of doing the LS swap consisted of removing the tired 350 motor and TH350 transmission and replaced it with a freshened up LQ4 motor (upgraded cam shaft), 4l80e transmission, new Holley Sniper fuel tank, and new posi rear end. My car went from all show and no go to the complete opposite with tons of power and reliability. I couldn't be happier with the work done. I've also taken my daily driver to John for typical maintenance work and I've also received good work for a fair price. I'll continue to take my cars to John and recommended him to friends and family looking for either custom work or general maintenance and repair.

    5 stars for Bob purely based on honesty, professionalism, kindness and customer service…read more I reached out regarding damage on my salvaged VW CC after a hit-and-run from an unregistered RV. Bob gave me a realistic quote, but more importantly, he took the time to genuinely guide me instead of just trying to sell me on expensive work that didn't make financial sense for my situation. Even though I'm probably not going through the full body shop route, he still went out of his way to explain my options, educate me on the differences between body work vs PDR, referred me to someone he trusted, and even personally vouched for me and texted the guy on my behalf trying to help me out. That level of kindness and authenticity is rare these days. You can tell Bob genuinely cares about people and takes pride in doing things the right way. If I ever needed proper body shop work done in the future, he'd absolutely be one of the first people I'd call. Highly recommend.

    If you want an experience where the body shop damages your vehicle and completely denies any…read moreresponsibility, a constant hassle of them saying your car is complete only for you to find that it's not, and for the timeline to be quadrupled then Bob's Bridge is the shop for you! The biggest problem is that they damaged my vehicle. No question about it. You can see the before and after pics with dates. My car had a small chip in the middle before the service but no chip on the left side. I know they damaged it because how I got the chip that in the first place because I slammed the trunk hard, thus chipping the glass. And this body work included fixing the trunk not able to close properly, so I'm positive they slammed the trunk thus chipping the glass in a different area. After telling Boris about the damage he completely denied responsibility and he has a way of not saying he won't pay for it, but rather pushing that issue to the side and saying we'll let's finish your body job and then maybe we can discuss the damage issue. But when the job was done I said he would need to compensate for the job and he said he's not paying anything. His defense was saying they don't work on glass so it's impossible for them to have caused the issue. But as I mentioned above, the chip likely came from somebody slamming the trunk. Additionally, Boris told me my car was done 6 times (yes, six!!!) when every time it was not. I don't live in Fremont so each time I had to drive to 45+ minutes, or waste money on Uber/Bart just to find out that the car needs to remain in the shop for further work. This is due to their poor craftmanship. You can see in the pics that they wanted me to pick my car up when there was damage on the bumper, poor paint job on the rear tailgate that made it red (they were so cheap on the job that they got aftermarket parts, so I didn't realize that they got a tailgate from a red tesla and painted it grey , which I never agreed to at the beginning of the job), sensors not being reinstalled, and the brake light was not installed correctly. Still, after taking it back 6 times, although most of the redness is gone there are still minor scratches that were never there before the accident. Boris has hung up on my phone calls so despite their "warranty" I'm not even able to go back there again so I'm just going to have to deal with it. The weirdest part about this whole experience was that one of the 6 times they said my car was complete they put on bumpers that had no holes for the sensors. So basically the tesla drove like a normal car without being able to detect what's in front or behind it. I still have no clue why they would do this?!?! Why would you put on the wrong car parts?? I told them to keep it in the shop but they insisted that I take my car because it would take a week for them to get the parts, paint them, put the sensors in, etc etc. Of course this took 2.5 weeks instead of 1 and then he didn't fix the sensor problem so I had to drive out again and wait another week. Ugh. It was such a hassle. And of course Boris was claiming that he had nothing to do with the sensors being a problem that they caused . Really Boris? The sensors were fine before I took it into your shop so please explain that one to me . Lastly, they said this job would take 1.5-2.5 weeks. It took 2 MONTHS. Yes, 2 months. And still my car has scratches and the windshield chip I mentioned. Not to mention I had to pay 100% of the cost up front which is extremely sketchy. Body shops only require 50% up front at most to buy parts. They claim that I had to do that because they gave me a good deal. I don't buy that one bit. Be weary they will also want you to Zelle so you can't dispute the charge!! I disputed the charge but unfortunately lost. I will be taking Bob's Bridge Collision Center to small claims court to recover the cost of them damaging my rear windshield. Avoid this shop at all costs and don't make the mistake that I did. They are liars.
