SLS Automotive Customer Reviews

Shane has worked on a couple of my cars, including doing an LS swap with transmission and rear end rebuild in my 63 Cadillac. Having been an active automotive hobbiest for more than 50 years, I've not found a more knowledgeable, detail oriented or conscientious mechanic. He's able to help visualize a project and bring it to completion. I will certainly continue to bring my classic cars to SLS.

Shane at SLS Automotive is the man to see about any of your classic car or truck needs! I do most of the work on my classic vehicles myself, but whenever there is something a little over my head, Shane is my go-to mechanic. He’s an absolute professional that puts pride into his work. He takes the time to do things the right way, and stands behind his work with excellent service and support. Shane’s prices are reasonable, and he fills such a valuable gap in the classic automotive industry by doing quality work, while still being affordable compared to some of the high-dollar show car shops out there. Not everyone can afford to spend $50,000 on their beloved old cars, but Shane’s services allow us gearheads to keep our old rides out on the road where they belong! Hit him up for anything from basic maintenance or repairs, to full custom frame-off builds!

Hands down my favorite mechanic shop in San Diego; Shane has been meticulously taking care of my 64 Pontiac, 59 Ford Ranch Wagon and 62 Ford Econoline van and I couldn’t be happier. Plus he’s a just a good guy all around; very professionnal, extremely knowledgeable and super friendly, SLS ROCKS!!!

SLS automotive guys are top notch. I have a 1963 Cadillac convertible that needed a transmission rebuild. Shane and his crew accommodated my very large vehicle at the earliest convenience and handled everything stellar. Their shop had a bunch of classics being worked on and these guys know their business. Shane followed up with me after the pull/install to check on a few minor details and make arrangements for me as a priority. That’s what you want in a good wrench/mechanic. Your vehicle will be in great hands no matter if it’s a classic or new. Thanks SLS.

Shane did a great job replacing aging bushings - always a bit worrisome having someone else work on your special vehicle. This was a first, and Shane was a pleasure to work with. Thanks again Shane !

Took my 1950 Ford Coupe to Shane for a no start issue. He figured it out in a few days and it didn’t break the bank. Can’t recommend him enough. Thanks again man!
