FAQs.
Still not sure? Call 301-401-6669 and we will talk it through before anything is scheduled.
My engine light is on — is it safe to drive?
A steady light is usually okay to drive to us; a flashing light means stop and call. We can diagnose the code quickly.
Do you work on my make?
We service virtually all domestic and import makes. Call us with your year, make, and model.
Will you explain the repair?
Always. We show you what we found and why it matters before you approve anything.
Tell us what it's doing.
We'll tell you what it needs.
Send us the year, make and model and what it's doing. We'll come back with a real diagnosis and a written estimate for your engine repair — and nothing gets done until you approve it.
