hi guys the xray t4 13 is still a great car, yearly change is only incremental , set up and driving skill are still the most important things at club level, at my club there are still a few t3's getting around and they are still competitive at this level, I would recommend Xray to any budding driver new or second hand , the quality of the cars blow all the others away, light and strong. biggest downfall is expensive spare parts, but the best thing to do is buy a used car the same year model as the one you have or intend to get, trust me you will end up a long way ahead.
cheers
