Ignoring the price difference are the LED headlight option far better than Xenons? One particular aspect of Xenons worries me - I used to have a BMW 330Ci with Xenons but to change them from UK driving to Continental driving meant a trip to the BMW dealer. Ludicrous but fact! My previous 535i had a switch. So one question is how you switch between the 2 modes on the A3? Is a pain to change or just a switch. The LEDs appeal because the GPS system knows where you are and changes them automatically!
