I'm a big VW fan, had a Mk1 Campaign and currently have a MK2 GTI. But you lot have missed the only modern equivalent to the MK1 GTI - the VW Lupo GTI. It is everything the Golf GTI Mk1 was - ie light, powerful and corners but with all the modern extras - VW build quality, reliable, air con, great sound system. They are destined to be a future classic. 6 speed gearbox, cheapish to insure. Post 2001 is a must, with the 6 speed box, still a number of original ones left.
I'm looking at getting a new car, my MK2 GTI is getting a bit wearing on my 1.5hr commute everyday. I would love to get a Lupo GTI, but I'm going with a Volvo V40 T4 - Estate so I can chuck the bikes straight in, leather, air con , cruise and to top it all 200bhp! If I had the spare wedge I would without doubt replace my Mk2 with a Lupo GTI and give it to my girlfriend.
