Anyone planning a build can read what a classic car restoration costs before requesting estimates. This profile is independent and Classic Cars Arena has no relationship with the shop.

Who they are and some history

The Better Business Bureau lists the business as founded in 2011 and still shows an older Clinton Township address. The shop's own news page says it moved from Clinton Township to Sterling Heights, where it says it occupies four buildings totaling more than 40,000 square feet. The shop states it employs more than 20 people and describes more than 200 combined years of technician experience.

What they restore

The shop says it works on American-made vehicles from the 1930s to the late 1970s, including classic cars, muscle cars, hot rods and motorcycles. Its site also mentions smaller restoration items such as pedal cars and golf carts. Documented client cars on its news page include a 1935 Plymouth convertible and a sport compact build.

Work done in-house

• Frame-off restoration and full classic car restoration.
• Metal forming and fabrication.
• Paint: automotive painting, airbrushing and custom finishes, plus ceramic coating and paint correction.
• Mechanical repair and upgrades.
• Collision and auto body repair, which runs alongside the restoration business.

Notable projects and awards

The shop says its team and clients earned six awards at the 2026 Detroit Autorama, three first-place and three second-place class finishes, with six vehicles entered. Its news page also records a 2018 Autorama where a customer's 1935 Plymouth convertible received a Master Builder Award and other cars took class awards. All of these are the shop's own reports, and several were won by customer cars built or finished there.

Working with the shop

The shop says it works directly with owners so they know the costs building up during a project, and that it keeps a direct line of communication throughout. It also publishes restoration documentation videos. We did not see published details on deposits or billing method, so ask at the estimate stage.
