Service & Repair

European and Classic Auto Repair in Lewiston, Maine

Portland Performance is an independent shop at 1830 Lisbon St in Lewiston. Our daily work is maintenance, diagnostics and repair on BMW, Mercedes-Benz, Audi, Volkswagen, Porsche and MINI, with the same quality of work on American and Japanese vehicles, diesels, hybrids and Teslas. We are also a destination for classic muscle cars and trucks, engine and transmission calibration, and detailing. We serve Lewiston, Auburn, Augusta, Brunswick, Topsham, Bath, Yarmouth, Gray and the towns in between, and classic owners from across New England.

Most of our customers come to us so they don't have to take their car to a dealership in Scarborough or Westbrook. You get dealer level diagnostic equipment and OEM parts, with technicians who explain what they found and show you photos and video.

OEM or equal quality parts

We prefer genuine OEM parts, or parts that match their quality, along with factory spec fluids, so every repair goes right and lasts.

Our workmanship warranty covers most repairs. Ask about coverage details for your job.

Frequently asked questions

Will servicing my car here affect my factory warranty?

No. You can have maintenance done at any qualified independent shop. We follow the factory schedule, use OEM or OEM spec parts and fluids, and document every visit. Every maintenance and repair visit is also reported to CARFAX, so your service history stays complete for resale, just like a dealer.

How do I get my car to you?

Schedule online or call. You can drop off during business hours or use our secure 24/7 key drop box.

Can you give me a second opinion on a dealer quote?

Yes. Second opinions are a big part of what we do, and a proper diagnosis often saves more than it costs.
