I was curious as to what cars others here have passed on purchasing that they really, really, really regret now? I'll start things off...advancing up my list would have been in '85 I passed on a '73 911 Targa, followed in '86 by a '67 MG, but my number one had to be an '66 Austin-Healey 3000 mk3 that I could have picked up (in 1987) for under $4000. Guess I could also say that when looking for a Boxster, I could have picked up the SE, but it was a manual, so I passed. I had also almost purchased (new) the last model year of the RX7, but ended up backing out because I feared the maintenance cost of a rotary engine...ironically a decade later I bought a Boxster.
This year I looked at and passed on a '02 Ferrarri... guess I am working on future regrets. LOL.
