If i allready had a mk5 i doubt i`d change it for a mk6,i agree there does not seem to be a massive difference between them,the mark 6 is probably a improved version of the mk5,thats just logical or why would they bother changing the model. this will be the First golf for me it just happens to be the mk6,one day along will come the mk7.mk5 mk6 both very good cars.
