I've had my car only for 2 weeks now but here it goes..
1. Engine + ZF 8spd : so smooth and effortless.
2. Xenon package : Love the look and all the automatic stuff (variable light distribution, high beam assist and turning lights)
3. No rattle so far! (touch wood) : Especially great since I'm coming from vw gti, that was a rattle box.
Run flat tyres: I have Goodyear eagle f1 asymmetric 2, not sure if other brands are any better.. may have to go non run flat.
