  • "These guys really know their cars, are very honest and have very reasonable prices. They gave me daily updates and even sent me photos, and when there was an issue they informed me right away. I am so happy with the work they have done. I know that these guys will be the only ones who will be doing any future work on my 1971 Mach1. Keep up the good work and if you are ever in doubt about this place don’t be you won’t find a better shop in town!"
    – Anthony H., San Diego, CA
  • "Got 3.80s with an Auburn LSD installed recently and I have to say, Current Auto Performance knows what customer service is all about! Not only was everyone there friendly, knowledgeable and fun. We even set up a weekend appointment as I work Monday through Friday. It was great talking cars while we were there and Bryant truly knows his stuff. Even though the shop is about a two hour drive from me, I’ll make the trip for anything I don’t have the tools or experience to tackle, as their work and service are top notch!"
    – Jonathan G., Redondo Beach, CA
  • “Finally found a great auto shop in El Cajon, after getting burned from other local shops. Bryant and the team at Current Auto Performance are extremely knowledgeable and fair. I definitely will go back for performance upgrades and maintenance.”
    – Ryan S., El Cajon, CA
  • “The best thing about Current Auto Performance is their honesty. I’m sure many of you have felt jipped after having work done at other shops. Whether you have a high performance car or a regular car they’re thorough, efficient, and knowledgable."
    – Natsumi T., San Diego, CA
  • "Wish I had brought my Chevelle here first. Had issues with the first two shops not being able to complete what they said they could. One company actually broke my dash and offered to install another for half price. Current Automotive Performance installed an automatic/manual valve body on the transmission, installed a transmission temp sensor in the pan, installed a new torque converter, installed a true trac rear end and gears, a disc brakes conversation, electric fan, and a Sniper EFI progressive throttle linkage update. Corrected numerous wiring issues. I plan on bringing my car back for any future work."
