Personally I loved the Mk5, both GTi and R32. Though, I wasn't too keen on the silver teeth of the Mk5 R32's, of which they copied for the Jetta's. These high-spec cosmetics should be individual.
The LED's on the Mk6 R's seemed almost 'desperate' to comply with the above. Other better options should have been considered, as these are almost identical to those on the Skoda Octavia RS-whatever. They might be all German now, but come on, VW is one marque and Skoda is quite the other !
In terms of performance of hot hatches, lets face it, VW screwed up with the Mk2/3-Mk4. They recovered with the Mk5 onward.
My Mk6 GiT is perfect for me and I love it, though its a shame that VW's standards have slipped over the past few years.....
