I went from an 03 STi with a few mods, to the MkV GT TDI Sport with DSG. To be honest, although the STi was a sub 5 sec car, the golf is a much better daily driver.

The torque is available from idle (almost) there is no lag (compared to the STi) and I get 900k's around town. I'm bloody happy with it.

The other car is an 06 Forester XT, it will eventually make way for another TDi I think (Tiguan or similar)

Take a test drive and see if you like it.
