The program, which launched last November after a pilot program, enables car shoppers to choose a specific vehicle, get estimated pricing, review available incentives, learn about financing and insurance products, get trade-in information and schedule delivery at the dealership or another location.
Shop-Click-Drive is now offered by 1,665 GM dealers in all 50 states.
The shopping tool provided participating dealers with more than 85,000 sales leads for new and used vehicles in its first year with an average sold and delivered rate of 30 percent, according to James Bement, manager of the Shop-Click-Drive program.
The service is most popular in the metropolitan Detroit, Los Angeles, Philadelphia, New York City and Chicago markets.
Bement said 49 percent of the trade-ins estimated through Shop-Click-Drive have been non-GM brands or discontinued GM brands.
Edmunds says: Car shoppers and dealers are giving thumbs up to this transparent way of shopping for a GM car or truck.
