A white 4wd would be the sensible choice, but they are so bland and look like....
'Silver' is just a tarted up grey
I know black is very popular but can't think of a single reason to have one except an attempt to look cool - which backfires in my opinion.
But if the deal is good enough it doesn't really matter what colour it is.
I nearly didn't buy my Jeep because it was dark green (wanted a white one).
Dark Green is a bad colour choice too but everything else ticked the boxes so colour became much less important and I ended up with it for which I have been thankful ever since - despite the short-comings of the colour.
