I had a MK6 GTI before my E46 and loved it.
Granted I had it between 40k and 60k over 2.5 years so was low miles but aside from coilpacks, it was flawless.
The 2.0 TSI is a robust engine capable of making good power with a remap and even stock performs really well with torque from almost idle.
Loved the DSG, and as I understand the wet clutch 6speed DSG on the GTI's is pretty tough too, just service it every 60k. Pretty smooth (not as smooth as a slush box at low speed) but with lightning shifts, rev matching and blips / farts - good times.
1.4TSI and 7 speed dry clutch DSG's are nowhere near as good.
We might buy another for the wife's next car TBH, the GTI's are a fantastic all-rounder.
Tartan seats FTW ?
