CRC CK25... Hands down best 1/12 pan car out of the box with great support from drivers from MN to MI (locally). I've owned Serpent, CRC, Associated, and XRAY. When Paul C ran Serpent and his brand of cars I would still recommend Serpent. Not sure if Paul C has been running 1/12 for XRAY, but that may change my opinion on XRAY now. Carpet is too far for me now but just sharing my .02
