Non-Mopar car you wish you had purchased?

Probably a hundred or so, most recent "should have" was an LS powered Austin gasser (at about half what I thought it was worth).
But the most memorable/regrettable? Was many, many years ago. .....
Was on a hotrod used car lot on Colorado Blvd in Pasadena. A corvette, with a powerglide. Don't sound much does it?
How about..... a maroon 67 roadster, wood steering wheel, side pipes, knock-off looking wheels (but weren't of course)...... and a Tripower 400hp 427 with factory a/c. (In a convertible! )The most powerful engine available that year with an auto trans.
Wanted $2500, would have taken 2200, but offered me $500 for my fuelie 57 with a fresh LT-1 in it. I passed.
That car is now an easy $150k.
