AKA, a sleeper.
And I love sleepers!
When my grandfather passed away in '84 I inherited his '72 Gran Torino. Putrid green in color, 32k miles (all of them City), perfect interior but rotted-out lower panels and rockers, 4 door, 250-6, C4, 8" rear end, plastic on the seats...you know the car. At the same time I was finishing-up building a "Clevor" engine (Windsor block, Cleveland heads, and Jon Kaase intake) that I was going to put in my '69 Mustang, but I couldn't help but listen to the Little Devil sitting on my shoulder that told me to put the Clevor into Grandpa's old car.....
I think out of all the cars I've owned, that may have been the funnest!
