Dropped the Volt off for the airbag check and battery enhancement service and got a loaded Buick LaCrosse to use through July 4th. This is basically a land yacht. I couldn't get a Vette but had a choice of 8 GM models. The dealer has a detailing company come in to detail the car and they're giving me 2 months of gas (6 gallons).... the downside, I filled up the loaner with $53 or what the Volt costs in fuel for 5,000 miles of driving... It appears you have to ask for the free detailing and free gas fill-up....
