I had a MK6...loved that car and never did any mods.
Not really a fast car but the entire package...torquey little motor that was smooth as glass, fantastic manual gearbox, great handling, easy and effortless to drive at 80-90% made it a blast. I especially liked sliding that car around on wet roads.
I'm not a fan of the awd version...didn't have the same feel to me. I suggest driving one...some folks fall in love, for others its not the right fit.
