Where we work, what to expect.
Spot-On's shop is at 4715 N Stahl Park, Suite 105, San Antonio, TX 78217. Drop-off only, by appointment. We work on one vehicle at a time, properly. The shop is north of downtown, easy access from US 281 and Loop 410.
The work that ends with the dealer saying "we can't replicate it."
Most of our retail work is second-opinion diagnostic: a customer arrives with a $3,000+ dealer estimate or a vehicle three local shops couldn't fix. We diagnose with manufacturer-grade tools, deliver a written repair plan, and — in many cases — resolve the problem for a fraction of the dealer quote because the actual fix is software, programming, or a bench-level procedure, not part replacement.
