Non-Mopar car you wish you had purchased?

In 1983 I had a chance to to buy a dark green 67 Z28 302 4spd for a 650 bucks.
Body and interior was perfect but the engine needed crank work( rod knock).
If I'd only knew then what I know now.
I also missed out on a perfect 67 GTX body for 135 bucks and 4spd for 25.
