Steve the Saintly One can tell you all about retrofitting Xenons as he has done so.
At the risk of sounding either like your dad or Captain Sensible, take it easy with chavs and those who want to race you, especially as a girlie driving a nice car is always a magnet (and something most of us find particularly attractive to behold). The law will, I think rightly, crucify you if they catch you racing. A buddy on here got big fines, big points, a 15-month ban, and was on telly and he wasn't driving dangerously but just very quickly in the company of a RS4 on clear dual carriageway. It's not worth it.
Ah, the special cloth. I suppose that if a lady says she's innocent, then....
If Hedge (Ian) doesn't explain I'll come back to ya after I've made myself a cuppa......... I had other plans for this evening before you came on!
