Your Earliest Fast Car Experiences?

Dad was "the" mechanic at our local Chrysler dealer from the late 60s tbru the 80s. He did a lot of side work, but never built a car for himself. One of his regular side jobs was a dark green Challenger RT. There was a half mile strecheck of road to nowhere that he used as his test drive route. He would air that thing out to ensure it was right. Me and the neighbor kid rode with him and the owner once when we were about 8 yrs old. The neighbor kid was terrified and went home crying. Litterally. When we got back to the house and dad handed the guy his key back, the guy told him he didn't know his car was that fast. Gave dad a big tip and rolled out.
