FAQ

What services do you offer?

We provide a full range of automotive repair and maintenance services — including diagnostics, engine repair, suspension & steering, brakes, oil changes, tune‐ups, fluid services, and more.

Do you work on all makes and models, or only certain vehicles?

Yes — we work on a wide variety of vehicles, including domestic and import, light trucks and passenger cars. If you have any specific vehicle make/model concerns, just ask in advance.

How do I schedule an appointment?

You can call us to set up a time that works for your schedule. For major repairs or diagnostics, we recommend booking ahead so we can have necessary parts and equipment ready.

Do I need to bring any information or documents?

Bringing your vehicle’s make, model, year, mileage, and any relevant service history helps. Also, describe the symptoms or issue you’re experiencing. That will help our technicians diagnose more efficiently.

How much will it cost and how long will it take?

The cost and time depend on the vehicle, the issue, and whether parts are needed. We’ll provide you with an estimate before any major work is done so you know what to expect.
