The VW scene is not the same as you may find with Jap cars. As Gavin said you may find there is not a market for certain parts like there would be for the SR20 engine. I think bolt-on type parts would sell better to the Polo guys.

There is not much choice for the Polo owners out there, not in this country anyway. Any new quality products would be welcome by Polo owners. But quality is a factor and some guys wont go for wank factor mods. A few of the guys here refuse to install an atmospheric (or semi atmospheric) type BOV. So the scene here is somewhat different to what you may be used to if you havent been in it.

The bonus is that there are a few models that run the 1.8T engine (with some variances in specs). The 1.8T engine in the Polo GTI has been used in Audi's and previous gen (MK4) Golf GTI, plus Seat's which we never got here in Oz.
