A neighbor of mine has a nice collection of mustangs and after i let him drive my fastback, he gave me a ride in his 500. It was a wimbledon white/guardsman blue 4speed 428 car. It was awesome. So much torque! The back end just wants to come around so much. It wasnt the fastest car ive been in, but definitely one of the coolest. This guy is cool cause even though he has the best mustangs you can buy, he drives the heck out of them, and he definitely wasnt afraid to step on this one. It was the first big block car ive been in too. Anyways, just thought i'd share! 

They are all neglected , but at least the Shelbys are inside. He bought them up in the early-mid 80s when they were dirt cheap. Drove them into a warehouse, cut the power, and left them there. A friend talked to him 3 or 4 times about buying a 67 GT 350 he has, but he wouldnt come to terms.
The guys a bit eccentric. It was all I could do to pry the 500 off him, and Ive known him about 12 years now.
