Customer Policies

Estimates and your OK

You get a written estimate before any repair starts, by text link or on paper. Nothing is done without your approval. If we find something else during the job, we contact you first. Your final bill won’t be more than 10% above the estimate you approved without your consent.

Diagnosis

Battery tests, brake checks and check-engine code reads are free. Finding the exact cause of a problem (diagnosis) is charged, and we tell you the price before your car goes into the bay.

Inspection

Every car gets a full inspection, featuring digital inspection with photos. We explain what we found and what it costs before any work starts.

Parts

We use new OEM or OE-supplier parts unless you agree otherwise. Some special-order parts need a deposit, which goes toward your invoice. Thinking of supplying your own parts? Ask us first: our warranty does not cover customer-supplied parts.

Your old parts

Ask and we’ll return them, except parts that go back to the supplier as cores or under warranty.

Payment and pickup

Payment is due when you pick up your car: card, pay-by-link, cash or Synchrony financing. After-hours pickup is available once you have paid by link; we’ll call you with the lock-box details.

Storage

Please collect your car within 72 hours of our “ready” message. After that, storage is $100 a day unless arranged in advance.

Warranty

Repairs carry our 24-month / 24,000-mile warranty on parts and labor. See our Warranty page.
