I know of a GNX with less than a mile on the Odometer. current owner ( at least I think he still has it ) gave strict orders when it arrived.
do not drive it outside of off the transport to the customer pickup area.
he picked it up with enclosed trailer and it has not seen light of day since

Ive not seen or heard anything from the guy in several years. But have my doubts he sold the car. at least not yet

Also, a friend of mine has a Turbo T type. with I think less than 15k miles on it.
he actually drives that one a good bit from time to time. Stock block and heads and I think its high 10 second car with only a few add on parts

Those cars are wicked fast for what they are
