trade my mopar for a pontiac??!!!

those second generation GM's are really growing in value- i'd like to find a mint 80-81 z-28 but there hard to find under 12K - my brother has a mint , immaculate 81 turbo black/gold interior thats appraised at 20K .those machos are pretty rare and the prices are definately on the rise - if you like it - get it
