GETTING STARTED

Know where to start.
Know what to ask.

  1. Tell us what you need.

    Share your vehicle details and the maintenance or repair concern. You don’t need to know which part is causing the problem.

  2. Understand the estimate.

    Some repairs need an inspection before they can be priced. Ask what needs checking, what the estimate covers and whether an inspection fee applies.

  3. Arrange your visit.

    Confirm an available time, whether the vehicle needs to stay, and your drop-off and pickup plans.

BEFORE YOU CALL

A few things you may be wondering.

Do you work on gas cars, too?

Yes. We work on cars, SUVs and gas trucks as well as diesels. Our services include oil changes, suspension and steering, engine and transmission repairs, and differential repair.

Do I need to know what’s wrong with my vehicle?

No. Tell us what you hear, feel or see, and when it started. Your vehicle’s year, make and model are a useful starting point. You don’t need to name the part that needs attention.

Can I get a price before bringing it in?

Start with your vehicle details and the work you need. Some repairs require an inspection before an estimate is possible. Ask what the estimate includes and whether an inspection fee applies. Get ready for your quote.

Where will the work be done?

At our Mt Pleasant shop: 20440 N 9800 E, Mt Pleasant, UT 84647. We serve Sanpete, Juab and Utah counties from this location. Call to arrange a time before bringing your vehicle in.

Does the online request book an appointment?

No. It prepares an email for you to review and send from your email app. The shop still needs to confirm an available time. For a conversation about the work, call (385) 685-8086.
