A Ford dealer in California that carried Cobras and Shelbys in stock. One day a man comes in and wants to buy a 427 AC Cobra roadster. The dealer tells him, I carry both the 289 and the 427 but I'd advise you to try the 289 as it's much easier to drive for most people. No says the guy, I gotta have the 427. The dealer gets the keys and they walk out to a beautiful white with blue stripes, Cobra roadster. They get in and the guy drives it a few miles, accelerating wildly and almost losing control a few times. They return to the dealership, the guy is sweating and a little shaken. He says, you're right, maybe I should try the 289 to which the dealer replies, that was the 289.
