Gainsbourg,
I just finished this kit myself, it is a very nice kit, but I don't think the colors you want to paint the body with are correct.
I researched the kit to make sure of the colors and found that the X-7 the kit calls for is the closest match to the actual car, also the Tamiya pure white spray is too bright for the roof. I would rather recommend using the regular gloss white acryllic or enamel paint.
