I think that the GT40 is unusual in looking extremely fast in a wide range of colour schemes, from the dramatic such as Pete's (bright exterior, splashes of interior colour, shiny wheels) to "authentic" Gulf, to bad boy plain or dark colours with black wheels, and everything in between. Your car has been built to a very high standard, and would look great in many styles.
Why not treat it to a re-paint every two years, to try some schemes? Probably you will be busy catching up with those house renovations and paint schemes instead.
Keep up the good work,
