Diagnose before we quote
We identify the actual cause on the car before any repair price is given.
You see the worn part
Whatever we recommend replacing, we show you the part and the wear.
No add-on pressure
We tell you what's needed now and what can wait, and let you decide.
A shop that shows you the part, not just the invoice
Performance Edge Automotive works out of a clean, straightforward shop in San Marcos — slate floors, drywall, chrome and glass, nothing trying to be fancier than it needs to be. The point of the room is the work, not the decor. When something's wrong with your car, we put it on the lift, find the actual cause, and walk you through what we found before any repair starts. If a part can wait, we tell you it can wait. If it can't, we show you why. Drivers come to us from around San Marcos and the surrounding area because that's the whole approach: diagnose first, talk straight, fix what needs fixing.

“Straightforward, honest assessment of my vehicle's repair needs. I brought it here after the dealership told me I needed over $4500 worth of work!”
last month
“I was befuddled when, on top of the $180 labor rate and total $424 repair cost, the first screen of the credit card terminal asked us to add a 10%, 15%, or 20% tip.”
last month
“Had taken my car prior to bringing it to performance edge and was told that items that I had on my list which included rear brakes that I needed to replace both drum and pads.”

Questions
How do you figure out what's actually wrong with my car?
We start with a diagnostic — scanning codes, checking the affected system, and putting the car on the lift if needed. We show you what we find before recommending any repair, so you're seeing the same thing we are.
Will you try to sell me extra work I don't need?
No. We check the car, tell you what's worn and what's fine, and separate what's urgent from what can wait. A Google reviewer noted the shop 'didn't try to upsell any additional service as dealers typically do.'
Do you work on all makes, or just certain brands?
We handle diagnostics, brakes, engine work, AC service, and smog checks across a range of vehicles. If you're not sure whether your car's issue fits what we do, call and describe it and we'll tell you.
