can the new r/t's hang with say STOCK 05-10 mustang and 03-04 mach 1. I know they are big car's but some people are managing low 13's from the newer ones seems like it would be a drivers race :??: magazines are saying 0to60 in just under 6sec but owners are saying more like 5sec flat after some seat time anyone drive or race one? I am strongly thinking of picking one up for a dd thanks.
