Most repair shops aren't staffed by liars — they're staffed by people whose diagnoser and repair-seller are the same business. That structural conflict changes what gets found, quoted, and replaced. Here is the same car, run through both systems, line by line.
Usually rolled into the repair you buy. A $0 "free diagnosis" is a sales appointment.
You, flat and up front — $150. We get paid the same whether you fix the car or drive it away.
A $12 trunk-light switch doesn't pay for the lift time. Bigger-sounding diagnoses pay better.
A $12 root cause found in 20 minutes is a finished job. We invoice, write the report, and leave.
Plug in a code reader, quote the parts the codes point at, replace and re-test if the light comes back.
Live-data analysis, circuit testing, and pin-point verification until the actual root cause is proven.
Discouraged. "That other shop doesn't know your car."
Encouraged — it's a service we sell. $95 to review another shop's quote against the car.
At their lot, work order in their system. You see it when they let you.
In your driveway. You watch every test we run, or don't — your call.
An estimate, then an invoice that quietly grew. Photos if you ask nicely.
A diagnostic report: DTCs, freeze frames, live-data evidence, the test that proved the root cause, and a repair path with OEM vs. aftermarket pricing.
Hard to say — "free diagnosis" visits rarely end empty-handed. Something always "needs doing soon."
If we can't find the root cause, you don't pay the diagnostic fee. Period.
Themselves. No choice.
Anyone you want. We hand you the report and the repair steps. Shops are welcome to work from them.
Every shop reading this page can honestly dispute any row except one: we do not sell repairs.
The order of operations is where the money hides. Test-then-quote and quote-then-test are not the same sentence.
The report is yours — DTCs, freeze frames, live-data proof, and the repair path. Take it to your dealer, your cousin's shop, or a parts counter. We don't hold your own diagnosis hostage to win the labor.
Already holding a $2,800 estimate? A $95 second-opinion visit spot-checks the claimed fault on the car. Needed, unnecessary, or not-yet — you get a straight answer.
$150 flat for a full mobile diagnostic. $35 trip fee within 25 miles of Canyon Lake. If we can't find the root cause, you don't pay the diagnostic fee. Period.
