eventually it was completely unreasonable, sporting a full race-trim 3.0l RSR motor, with an exhuast to match, and the biggest rubber he could get under the stock fenders (which was surely nowhere near enough for that kind of power).  i always knew when dad was coming to pick me up, because i could hear the car from half a mile away.
he finally got tired of this wheeled offense against decency (lord knows, if i could hear him coming, so could the local constabulary), and moved on to (i think) a jaguar sedan.  many years later, i asked what had become of the 914:
"I sold it to a local guy.  One day he tried to get away from the cops - of course they eventually caught him. Took twelve cars and a helicopter, but they finally caught the poor bastard."he tells me the car is still kicking around northern ohio.  i'd love to get my hands on it...
