Originally body colored, but mine are alloy too, and I prefer the look__keeps it "lighter" looking. I mean look, all the BJ7 & 8s were chrome (were the 100s plain aluminum as well?).
Eighteen Hundred Dollars ($1800.00) typically won't cover the cost of materials__well, barely, depending on pigments (yellows & reds being most expensive) plus assorted abrasives, compounds/polishes, not to mention exotic primers, sealers, solvents, catalysts, etc., etc., so yes, a smoking deal! And, it looks great from here
Just keep the car in motion, only dipping under 45 mph when unavoidable, and people will see (and hear) one of the most visually appealing cars ever produced!
