HI TOM....regarding the smell of fuel one of the guys on the uk crossfire owners facebook page reported one of the fuel lines coming of the fuel pump had been rubbing something and was nearly worn through, it was about 6" from the pump, as for wheels i think a refurb is about £50-60 per wheel then the cost of tyres, depending what aftermarket wheels you want as to price, i went with mandrus which are specificly designed for MB cars so didnt need spacers, offsets for our cars are front +35, rear +22 you need to get as close to these as possible, make sure you do your research to avoid costly mistakes...read through this it might help as to what will fit...https://www.crossfireforum.org/forum...hat-works.html
