here's my opinion.
1st you have a nice car no doubt, but from the pictures I'm not for the following:
A. red seat belts - 1st it does not match the red tone of the car. 2nd I think the black belt would look nicer a preserve the classic image of the car
B. red rear drum brakes - again I'd go for black. the red drums just draws the attention to that area which if you think of it, is not worth it as drums are not "race" type technology.
Am not against the color red, I had red '69 beetle once, very similar to the one you have. I just think that a good looking car should have the right color scheme and tones in the right places.
just my thoughts
