I'm almost 50 years old so I've had a few nice/interesting cars in my day.
There have been several times that I've said, 'I wish I had that car (or truck) back'. I usually say that after I hear how much they're worth now.
My first car was a rusty '69 Impala with a big block, auto and hidden headlights. It turns out it was pretty rare. I sold it to a buddy's younger brother for $50 and a set of Cragar mags after the tranny went out.
It was just another used car when I had it.
As the years went by, some other cars of note were (in no particular order):
'67 Pontiac GTO
'66 Plymouth Belvedere
'69 Chevelle SS
'67 Plymouth Sport Fury
'71 Buick Gran Sport
There are others but, you get the idea.
Before anyone says 'pics or it didn't happen', I doubt I'll be able to find pictures of these old cars of mine. If I did, I don't have a scanner to copy them here. If you can't take my word that's O.K.
The real point of the thread is not me but cars that others wish they had back for whatever reason.
On a side note: One of the reasons I UE abandoned farms is to find these old cars. I found a '65 Buick Riviera last year. It's still there. The farm wasn't exactly 'abandoned'.
