I haven't owned both but one of my mates has.His sapp was all singing and dancing it was 550bhp,2wd and black (so the best) and he was into it for about £30,000 until he killed it.He then got the skyline thingy and tried to get me to buy one,erm nope ! Go and get a cheapish 3-350 bhp sapp 2wd and have it hanging lol,go on you know it makes sense .As sad as this sounds,it will be a sad day in my household if I ever have to get shot of my Sierra.Also before anybody spouts off about buying a cheap one saying you will pay double,I am pretty sure someone with your capabilities wont have a problem .Is the RS1600i all done now mate ?
