Generally if you are half decent with negotiation you should be able to do better then 1k off anyway. Sounds like you got an ok deal...dont be too upset mate you got yourself a great car :)
Ive got an 04 and no its not necessary to remove the front bumper. You just have to unscrew the black seals behind the head lights, unclip that pin thing and replace the bulb. It sounds easy but it...
Using the 4000k Phillips one they are street legal and very happy with the result...i paid $59 from Autobarn. Install was easy but was a bit fidley. Also came with parkers.
I was sitting at the lights stationary the other day and a small deflection left or right of the steering wheel cause a slight rise in engine rpm...whats this? Is it anything to worry about?
