On Barbie? Nowt.
On a car........
Hmmm.
But, as with all things MG, whatever you like I suppose. It's your own car.
Each to their own choice.
But, please note these facts, that I probably just made up:
It's a little known fact that Steve McQueen wanted a pink Mustang for the Bullitt LA chase sequence, but the director insisted on green. The car was originally fitted with eyelashes around the headlights, but they fell off. Over the bumps. Fact. The baddies were meant to be in a baby blue Dodge Charger too, but they couldn't find one in time and had to settle for black.
Mad Max wanted a pink Ford Falcon with led's around the supercharger intakes but was over-ruled.
Colin Chapman, in the 60's, favoured pale pink paintwork for the Lotus cars but sponsors chose the absolutely rubbish red, white and subtle gold coach line livery, that everyone hates, and isn't in the least bit iconic, instead.
Same with the black and gold F1 JPS paint job. Appalling.should have been pink. Black and gold: rubbish.
And Herman Goering wanted to paint the all the Luftwaffe planes pink, but boring old Adolf had other ideas, So the RAF put out this little number just to make him jealous!
