Do you have the FR? allen?
You will get your money back. The two important options are 18 wheels on the FR and bluetooth on all Leons and Alteas
Are 18's going to be slightly more fuel efficient? I would imagine so - as with the tyre being a greater circumference it covers more distance per revolution? therefore a everso slightly higher average mpg in the medium to long turn? Or am I being silly here? I don't imagine changing my tyres much, in the first two years surely it's not necessary.
In case you haven't guessed I'm still trying to decideIs the harder ride of the 18s pretty much unnoticeable to the untrained driver?

I am very happy with my 17" wheels, and the ride is not as harsh.
got the price I wanted.then bought my 18inch Cupra wheels(They were brand new in mint condition) from a SCN member for £500
.Ive got 16" Wheels on at the moment (18's in the garage for winter!!) I can say there is no noticable difference in ride quality..
18's Definately...
The auto-dipping mirror is pretty good, but I cant stand the auto-wipers and lights personally.. And the mirror is (presumably) retofittable.
