Dilema

I totally agree with painting it black. You are doing the restore for your enjoyment, not as an investment. What's the difference between this and someone doing a similar restore but putting a new engine in it, with the original engine stored in the corner of the garage. Although a hassle, changing the paint back can be done at any time. Actually, since it was already a black interior, changing it back at some future date isn't all that difficult.
Go for broke! I mean black!
