When we had some waranty work
We were given a brand new (it had 30 miles on the clock) Malibu, with absolutely no gas in it, it was awful. no guts at all
the best was when we called the dealer he said he wanted to keep the car overnight as they had only been on two tests drives and wanted to make sure the car was right, they took it for another test the next day.. sure enough we had another 100 miles on the clock !!
