Santa Monica-based TrueCar, the online car buying service led by Scott Painter, has acquired the domain name True.com, which it says will be using for brand expansion and as an umbrella domain name. TrueCar did not say exactly how it intends to expand its service. TrueCar offers up a combined service which both provides end consumers with actual pricing data on automobiles, but also helps to connect those consumers with car dealers. TrueCar powers car buying programs for a number of membership organizations, including Consumer Reports, the AARP, AAA, USAA, and AARP. Financial details of the acquisition were not announced.
