So, I'm buying my first car soon. It's my neighbors 1969 mustang, I'm in highschool and its a bit of a fixer, anyways, it's white and I've always believed that these old mustangs look best in black. So, if I had it repainted black at a professional paint shop will the appreciation rate and historic value go down. I know if you put A/C or anything new in the cars it goes down.
