GM wants to expand its Shop-Click-Drive system. The automaker netted about 1,000 buyers after while piloting the program; however, fewer than 10 used the application to buy vehicles without going to a dealership.

The National Automobile Dealers Association is skittish about such efforts, because of the likelihood that dealers will be cut out of the question. Why go to a dealer when you can do the transaction online?
