I bet a Chevy Vega would fetch for a decent price these days, provided you can find one. I recall reading about how most rotted away within two or three years after buying brand new.
The Vega is something that will keep me up at night. I had a 77 Cosworth Vega. I actually financed it in 2010. Reverse H shifter, white interior.
Got stolen. I developed a crack in the timing belt (Which is very, very rare to find for the Cosworth) and had it parked for 6 months.
