Had full leather in my last mk5 GTi, and there is no way I'd swop the ED30 seats for them. The leather looks ok and adds a bit of class to the interior but Id say the ED30 seats are comfier and you don't get the hot in the summer/cold in the winter issues.
I was a little unsure of the ED30 tartan leather combo when I looked in the brochure before I bought mine but the pictures don't do them justice and they look a million dollars in the flesh.
Has anybody seen the Recaro R32 styley seats with interlagos cloth centres at
www.fischermotorsport.de, they are the b@@llocks, but at a price 2200 euro's each!!! makes me want to keep an eye out for some R32 recaros and have them retrimmed to suit.
