<font size="2" face="Verdana, Arial">i think it's a rather good idea so that you get to know the car better before you buy it, but i wonder if the dealers are going to be truly happy about this.DETROIT - A new General Motors Corp. incentive will allow car and truck shoppers to test drive a vehicle overnight.
The offer will last from April 15 through July 31 and will apply to nearly every GM model, excluding the Hummer H1, Cadillac XLR, Chevrolet SSR and Chevrolet Corvette, company officials said.
Customers may test drive the vehicles for 24 hours and are limited to 100 miles. The vehicle must remain in the dealer's state.
Drivers must leave their current vehicle at the dealership and must have insurance and a valid driver's license, McGee said.
