What you get

Four promises attached to every estimate

Transparency isn't a slogan here — it's the paperwork we hand you before you spend a dollar.

Written estimate, every time

Line-item parts and labor before a wrench turns. If the number changes, you approve it first.

Photos of the actual failure

You see the cracked injector cup, the scored bearing, the melted connector. Not a description of it.

Diagnostic time credited

Diagnostic time is billed at our posted rate and comes off your repair when we do the work.

Free local towing

Major repairs include free towing inside the Temecula Valley. Don't drive a hurt engine here.

Common requests

What people usually ask us to quote

Pick the closest match in the form — we'll sort out the details on the callback.

No approval, no work

Your estimate is a ceiling, not a starting bid. If we find something else mid-repair, the truck stops and you get a call.

Questions

Before you send it

Is the estimate actually free?

Yes. Quoting your repair costs nothing. If the truck needs hands-on diagnostics to find the fault, that time is billed at our posted rate and credited back toward the repair when we do the work.

How fast will I hear back?

Requests sent during shop hours get a same-day response. Anything sent after hours is answered the next business morning.

What should I include?

Year, make, engine, mileage, what the truck is doing, when it does it (hot, cold, loaded, highway), any stored codes, and what's already been replaced.

Do you work on gas engines too?

Yes. Smog work is what we are known for, but we service cars, trucks, vans and fleet vehicles on all makes and models.
