I ordered a 2010 Golf TDI. I am 1st on the list at my dealer. When the 1st Golf comes in I can accept it or reject it if it does not match my request . I did not list the Xenon headlamps but can accept a Golf with the xenon lights if it is on the 1st car to arrive. Are the Xenons worth $700? Does the VW system lights move the beam in the direction you are going when turning?Do they self level if there is a load in the rear? Can after market Xenons be added at a reasonable cost ?
