Interesting approach. I think it will work for the Malibu, which everyone loves once they actually drive it.

Frustrated that many shoppers won't even consider its cars, General Motors says starting Monday, buyers of new GM models can bring them back within 60 days, no questions asked, and get back the price of the car.

I assume you get the sales tax back too?

Pretty cool idea - I agree with you with about driving the Malibu and loving it - the only reason I considered one was because I picked one from the Emerald Isle last year on our trip to Disney and loved it !!!

Damn good idea! CarMax offers 7 day money back guarantee, making a lot of buyers to come to their lots (including me). GM can reduce their Ad to cover the refund expense!
I am curious that what they will do with the returned cars. Probably sell them cheaper like the "open box" items? But that could cause a backfire as many can just take time, wait for these cars, instead of buying a new one.

Yeah it will surely Work for it. people will prefer it.

damn, wish they offered this in canada!
