Half the cars on the road seem to be that colour and unless the cars have DRLs on it makes them hardest to see against the grey of the road surface. From a financial point of view I wouldn't worry buying 2nd hand. But I'd think twice about buying new. I bought my FIAT 500 in Bossa Nova White because it looks good that colour with Tricolor sidestripes. The wife has just had her Toyota pimped from black to pearl white with a bodykit, 17” bling wheels, red multipot callipers, etc. Bit embarrassing for me to drive, but it looks okay.
