Hi, I'm looking to upgrade the tatty stock plastic wheel on my 1.4TDi sport with something nicer, preferably leather. I understand the Lupo GTI, the SE and the Polo 6N2 GTI are all straight replacements. I have the option of a 3L (with airbag) but don't know if it a straight fit or whether mods are required. Can anyone offer any wisdom / experience please? Cheers.
