Colin's Classic Auto

Colin's Classic Auto is a collector car dealership in Milwaukee, Wisconsin, run by Colin Comer, an author and appraiser who has spent more than 40 years in the collector car world. The business says it began in 1991 as Colin Comer Automotive Services, working out of a two-car garage, and became Colin's Classic Auto in 1993 when Comer went full time and rented a 1,500-square-foot shop. The Better Business Bureau lists the business as starting in 1993.

A one-person, selective operation

The company describes itself as small by design. Comer works largely alone, deals directly with buyers and says he sells only cars he considers among the best of their kind. His site says he welcomes pre-purchase inspections and provides full vehicle history and condition disclosure. This is a dealer selling cars it owns, not a consignment lot, and the inventory is deliberately short. Visits require an appointment.

From restoration shop to dealer and adviser

According to the company, the shop eventually grew to 22,000 square feet with in-house restoration capabilities and worked on cars ranging from prewar models to 1960s Ferraris and muscle cars. Comer says he stopped taking customer restoration work in 2019 and continues with personal projects. The business now concentrates on buying and selling, along with appraisals and consulting for collectors.

What it sells

The focus is rare, high-quality collector cars, with a strong thread of Shelby Mustangs and Cobras, other muscle cars and Porsches. Listings on the dealer's inventory pages have included a 1969 Shelby GT500 Drag Pack, a Kirkham-built 427 S/C Cobra, a 1994 Porsche 911 Turbo 3.6 and a 1970 Jaguar XKE, according to search results for the site. Cars at this level often cost well into six figures, so documentation and originality matter more than usual. A prospective buyer should expect to review build sheets, ownership history and period records, and to bring in an expert for an independent inspection.

Expertise and books

The company's about page lists six books by Comer, including Shelby American: 60 Years of High Performance (2023), Shelby Mustang: The Total Performance Pony Car (2019), The All-American Muscle Car (2013) and The Complete Book of Shelby Automobiles (2009). Sports Car Market lists him as its resident American car expert, and the company says he has judged at Pebble Beach and served as chief judge of the Milwaukee Concours d'Elegance. Those are the company's and publisher's descriptions. Buyers should still weigh each car on its own evidence.

Reputation and licensing

The BBB page for Colin's Classic Automobiles shows the business as not BBB accredited and not rated, with no complaints closed in the past three years and no customer reviews posted. That is neutral rather than a recommendation. The Wisconsin Department of Transportation dealer list, refreshed on October 1, 2026, shows Classic Auto LLC, doing business as Colins Classic Auto, as a licensed dealer at the Milwaukee address, with a license running to March 2028.
