Golf R all day for me. It has the k04 bolted to it, and coupled to a 4wd system, Even with a remap on a GTi, do the same just by one stage, you have an absolute weapon in the R. The same comparrison between k03 mk5 and Edition30 with the k04 turbo.
It take just £400 to transform a GTi to better performance. But do the same for the same ammount of money on the R, and you have a properly fast car that most things on the road would find it hard to live with.
Power is no good without Traction. Something my Stage 2 Edition30 needs!!.
Exclusivity is another + on the R. Because they are priced high, not as many being ordered, but im sure will help 2nd hand values later on.
