As a teenager in the '60s, I had pics of GTOs, 'Vettes and Jaguar XKEs on my bedroom walls. Adult life took over and I never got to own one of my dream cars. I had a girlfriend who had a souped up, 500 hp GTO with a 455 though that could rip your head off.
In 2003 I had "matured" enough to get my wish and I bought one of these 1999 supercharged DOHC V8 Jag XJRs, which I still own w/70k miles on it:
With 370 HP, 390 ft/lbs. torque, 13.2 sec. 112 MPH 1/4 mile, 155 mph top end it stands pretty tall as a muscle car. My own private joy ride.
