(Obligatory "car culture is cancer, build public transit, etc")
My white whale is a 1986 Mustang GT, manual transmission. Had a chance to buy one for absolute peanuts in 2018 (at least, compared to their price now!). Was completely stock too, no mods. But the mechanic I hired to inspect it warned me off it because of its age...
1986 is the only year that came with fuel injection but still has the old "four-eye" styling. Realistically, that car was probably not right for me at the time, but man - it will forever be my one that got away
