tbh, the mk3 4 and 5 are all in the wrong direction from the original golfs.
the mk1 was as has been said, a ''toe in the water'' excercise. the mk2 was the refined version.
so all this argument about insulting the mk5 by doing this toa mk4 doesnt matter, because the real argument is, why the hell hasnt the guy sold it and bought a mk2?! then used the spare cash to dump a 20vt in it? then not even a remapped tank, sorry, mk5, would even touch it...
mk5 owners - more money than sence...
all above is just my opinion...
