I have been very fortunate to have had quite a few really great cars, especially in the last few years.
My first car though in much humbler days was a 1974 Mustang Coupe.
But my favorite, as a young gun at the University of Colorado, was my 1979 Jeep CJ-7 Renegade.

It was black with orange gradient 'Renegade' striping, white wheels, all terrain tires and a wicked AM radio!
I had the back seat removed, laid some thick orange shag carpet on the floor (for cushioning) and had my bud Dan Delaney (Dan now paints indy cars)paint the side inside wheel well with 'The Flamingo Lounge' (For the ladies I entertained back there).
Oh baby!
I thought I was killin em back then!
What was your favorite and why?
