It's strange but in the mk5 and mk6 heydays there was a raft of retrofitting and I bought my first mk6 pretty standard just because I knew I could retrofit just about everything at much less cost than vw were charging as options.
Since the mk7 launch its all gone quite quiet in general with modifications.
The whole feel for modifying seems different.
I've hardly touched mine in 15 months. That would have been unknown years ago, I'd have had the thing apart and fitted all sorts.
Maybe VW's anti tamper software in certain parts of the car (ECU, nav) is putting people off in general?
