'69 Cuda I bought in high school and drove weekly for over a year before tearing it apart, finally broke down and sold it last year. I wanted to make a Pro-Street car, but had like $40k to go on the build and no time to do anything so it just sat... and sat... and sat. Current owner did a frame-off reso-mod out of it. Not my cup of tea but at least she's getting taken care of.
This was my '72 Demon resto-mod, and I sold it too, but this one's still in the family. My dad now owns it and has is doing great things with it.
And before you laugh, this was an 11-second Crossfire I sold in '09. Maybe not "muscle car" enough for some of you but it ate Corvettes and shit Supras.
The Dakota you see in a couple of those pictures looked stock, but ran 13.90s with a Vortech supercharged 5.9L swapped in from an R/T. Detroit locked, beefed NV3500 5-speed, 3.92s out back with 4.01 1st gear, 3" true-duals from custom equal-length long tubes... Stupidest vehicle I've ever driven. The thing was out of control, no weight over the rear, locked, with 365 ft-lb of torque as low as 2,200 RPM... Ah, needless to say I wrecked it a couple times.
