YouTube - MUSTANG GTR
I had a friend, one time, call me from a dealership telling me there was a '99 Cobra for sale that I should go look at. He said the salesman said it was supercharged and everything. So I get to the lot and ask what kind of supercharger is under the hood. The salesman says "Ford..."

. I tell him that Ford has never made a blower (that I'm aware of) and the only mustang to come with a blower from Ford is the 03-04 Cobra (this was before the GT500). The salesman swears up and down that there is a blower. So I ask to see under the hood and he grabs the keys and opens it up. Within seconds I can see that there is no blower. So, playing dumb, I ask where it is. He points at a piece of equipment and says right there. I very politely respond "That's the alternator..." He then starts frantically looking for a blower that doesn't exist. I let him search for a couple minutes and then explain to him that there is no blower, if there was one, you would know. He looked very embarassed, so me and my friend just took off... but not before driving it of course:3gears
