Are you sure you want white with winter coming?
A friend had a white Esprit, we came out the hotel one morning, and couldn't find the bleedin' thing, snow fall of about 2 ft.
Having said that, the best bit was watching him clear the car (when found) in his wifes high heel boots - he said it gave him more grip
Personal opinion, the Z has chrome, and white would not show it off as much as a dark colour, but hey its all down to personal choice.
