Frequently asked questions
My check engine light is on. Is it safe to drive?+
If it's flashing or the car runs badly, stop driving and call us — it can damage the catalytic converter. If it's a steady light, book a diagnostic soon. We test to find the real cause before recommending any repair.
Do you work on trucks?+
We work on pickup trucks and SUVs, including commercial pickups. We don't service heavy-duty trucks, semis or large commercial vehicles.
Do you offer financing for big repairs?+
Yes. Financing is available for larger repairs, so you can fix your car now and pay over time. Ask about it when you call or book.
