Hi there guys don't know if anyone else is interested in these things but there has been a good increase in 1/18 models of GTI mk6s on Ebay.
I've now ordered one in Tornado Red (my colour obv) so I'll confirm the quality in a couple of days. Most of them are German sellers it seems and the company behind the models is usually either Shuco or Norev. Both of which I believe supply the models to VW dealers for display cases.
I love my car collections at home (still a small boy ha ha) and like to buy a model of every car I own.
Just thought I'd stick this up in case it takes anyone elses fancy.
