I think I paid about £600, fitted. It was a new Golf R Mk7 wheel with the round airbag and DSG paddles. I know that loads on here have done it themselves much cheaper, but I was a T6 novice and didn't want to touch it.
There should still be lots of Euro5 type of wheels available as the Golf Mk7 has been around in high volumes for sometime.
There's a thread somewhere in the interior forums with much more detail if you fancy some DIY.
