My parents bought a brand spanking new 67 Chevelle Malibu in 1967 for $2900 + or -. I was 17 at the time and I ran the guts out of that car for two to three years, 283 2bbl, auto. They kept the car up until about five years or so ago when my dad put it in the news paper. He was thinking of asking $1500 for it. It had been in a number of minor fender benders and had an Earl Shieb paint job. The original 283 was still running great with about 160K on the clock. The trunk floor was just about rusted out. I told him he could get a lot more than $1500 for it and he should ask $5500. The very first guy that came by bought it without any hassle. He promptly turned it into a SS396 clone. I see it occasionally on the street and at some local shows.
It is hard to make an estimate of what the car is worth based on the pictures, but I would think it was worth at least $5000.
