I sometimes go to Ikea in Sheffield, Opposite is a Mercedes dealership and a Porsche dealership. The Mercs are all some shade of grey and look so boring, The Porsches are about half greys and the rest are vibrant bright colours that look much more fun and interesting. If I was in the market I would ignore the Mercedes dealership.
Go to a manufacturer website and look at the colour options, They really are very bland for the most part. You have to buy a sporty version quite often just to get good colour choice.
This is partly why when I painted my own cars I have a strong blue, bright yellow and bright metallic red. My Mrs Fiesta is some kind of pearl green.
Bring back the colours!!! Viva la revolución.
