Not sure what kits on it, thats the way i found it, not very clued up on these things at all, yeah i think the grey would become boring very quickly and you have to work hard at giving it a nice shine, i think the blue does look better, although the grey ones seem to be quite rare, i was looking for 4 months to find a new car and i only saw one grey one with the sports kit. good luck with your search :D
