Have had this happen many times. When I went to go get a lightning a couple years ago I went to a dealership here in town. Told them I am here to buy one of your lightnings,worked the numbers and then told them I wanted to test drive it first, immediate problem. They wouldnt let me test drive the truck at all so I told them to enjoy the truck and I will go elsewhere. Made a call to jack Demmer Ford in michigan, ordered my truck and when i went up there to pick it up they threw me the keys to one and told me to take it for awhile to make sure i would be happy with the truck. Went back and signed the papers for my new truck. A year later was up there for a visit and stopped by the dealer to look at a cobra, they had no problems letting me take it for a drive. The chrysler dealer in town here is the same with there SRT's, they have all of them on the show room floor and wont even let anyone sit in them unless they fill out a credit app. Rediculous if you ask me
