No contest here (for me atleast)
Nissan S14 V8 :
The S bodies are supposed to be very good chassis's for drifting with. Plus it has a V8.....
Toyota AE86 turbo :
I have always had a soft spot for these. Not sure what engine it will have in it though as it says turbo. But the original 4AGE engines are just wonderful. My old MK1 MR2 would rev to high heaven! Plus this is the original drift car (see Initial D movie). So extra cool points here.
BMW E46 M3 - does nothing for me
Nissan 350Z - owned (not drifted) one of these so would be good to try the above cars as they are new. However, there could be something said for drifting this car as it may provide skills that can be transfered to the 370 for real road situations and car control.
