In my opinion, the MK7 GTI (which i really like) shouldnt be any dearer than 25k. Especially with just 220-230bhp which is a bit behind the competition. The Golf R shouldnt be any more then 30k, especially with the M135i being so affordable and with over 300bhp!!
If they are any more expensive then my estimations I personally think they will be over priced, which would rule me out. I would just give other manufacturers like Mercedes, BMW etc my custom. I never though I would say it but at the moment the luxury brands are turning out to be quite reasonable.
