The two cars are identical, but for one minor detail: the serial number.
One them has a serial number that ends in 01, the other serial number ends with 212.
The former, pictured here, is in the Henry Ford Museum in Dearborn, Michigan.
The other one for sale at a Chicago area muscle car dealership.
Both are claimed to be the first Mustang ever sold to the public, back in 1964.
The museum Mustang is not for sale.
The other Mustang is for sale, with an asking price of $5.5 million. According to the dealer, it was actually delivered to its purchaser the day before the first day on which the Mustang could be officially sold.
And, of course, that’s where it starts to get murky – because all but about $50,000 of that price tag is ostensibly justified by the car’s status as the first production Mustang sold to the public.
