I went for the phoenix as its something different from the usual black, silver etc....After viewing an E46 M3 in phoenix i started looking for a coupe and eventually found one. I agree it is a love it or hate it colour but it ticks the boxes for me and looks very good in the flesh when its clean....
A couple of friends from the Clio V6 owners club had the Acid Yellow and Liquid Yellow variants on their Clio's and again these looked awesome in the flesh / different from the Silver, Blue, Black standard colours..
