You can have your cake and eat it. If the colour you want is too wild for most tastes, then order a 'sensible' colour, then just get it wrapped in plastic, any colour your heart desires, it will protect the original paint, and can be removed at sale time like a chameleon shedding its' skin.
Additionally, a lot of little extras like union jack badges, better steering wheel, full windscreen, etc etc can be added later and for a lot less money than MMC will charge you. It will then truly be your car, specc'd by you and modded by you.
You know it makes sense, go for it.
