Angie’s List sees an open road ahead when it comes to providing its customers with ratings on classic and custom cars.

Today, the Indianapolis-based consumer ratings service will announce that it is soliciting — and in turn will offer — reviews on businesses that provide services for classic cars.

Angie’s List car-buff customers will be able to search more than 100 categories, including painting, plating, polishing, wiring and welding, according to the company.

“We’ve heard feedback from our members that this is an area of interest for them,” said Angie Hicks, Angie’s List founder. “Not only is it an expensive investment, but it’s also an emotional investment. . . . It’s really important for them to get reliable information for the service providers they’re hiring.”

Angie’s List (angieslist.com) allows its 1 million-plus members nationwide to submit and read reviews on an array of services, including plumbers, painters and pediatricians. The company prohibits anonymous reporting.

Typically, Angie’s List members would view service providers from their own local area. But the new Auto Restoration Services division will have a national focus because people looking to have a classic car restored are likely to search beyond their own city, Hicks said.

She added that Angie’s List plans to offer more national ratings in areas such as house restoration.

Bob Coulston, a member of the Mustang Club of Indianapolis, said the new service from Angie’s List could provide a useful tool and put pressure on shops to do quality work. He said many people join classic car clubs mainly to ask other members where to get work done.

Such work isn’t cheap. Coulston, who has four vintage Mustangs, estimates it could cost from $30,000 to $50,000 to transform a poor to mediocre Mustang into a shining gem.

“The price goes up every day,” he said. “Parts are harder to find.”

Ron Vail, owner of the classic car restoration business Vail’s Classic Cars in Greenfield, also welcomed the idea of a new ratings service.

“Anything that makes you stand out,” he said.
