was just thinking about how nice the new age vw gti (polo and golf) interiors look

You know the nice steering wheels with the straight edged bottom......On a 6n maybe?

Also

Dials.. I've noticed on google images some people have managed to fit audi s line dials onto a 16v 6n, since there identical, is there any others? and is it much work?

You can fit pretty much any dials into pretty much any car, but its very rarely easy.

But like I'm thinking of fitting some audi stuff like the tt pedals and fuel cap, R8 oil cap, and i know you can fit the TT dash with work...But what about any other dashboards??

And steering wheels as well
