When I wan in HS, my friend's mom said the same thing. He wanted to buy his neighbor's Torino GT (a la Starsky & Hutch), but she said it was too fast. Instead he went out and bought a '77 Grand Marquis wagon (the one with folding headlights and the wood on the side), bought the motor (351C) from his neighbor's Torino, and we put it into his wagon in shop class. He didn't even bother to paint the wagon. It was ugly yellow, had woodgrain paneling on the sides, and no hubcaps.
Needless to say, his mom wasn't amused. He did get to keep the car through the winter. It wasn't that fast, but that thing could smoke the tires for days, and it could do donuts anywhere. He went through nearly all of the 15" tires that were laying around the HS auto shop that winter.
She made him sell it in the spring, and he bought a Dodge Omni GLH-S. Basically, the moral of this story is that his parents turned him into a ricer.
