Yeah Ern's right there, i like alot of us on here have had the 48 55 and now my current 63, if i'm being totally honest my old 3dr on a NMS Live Map with the .48 housing on was probably the best road cossie i've had for pound for pound punch & fun, the .63 pulls harder than the .48 but alittle lazier at doing so, BUT not dreadful lag as somw will have you think..
