That seems pretty good! I am thinking of changing my head unit so I can play DVD's, I never imagined I could get £300 if I got rid of my Bose head unit!?!? Or have I missed something!?
Wouldn't go near AA or RAC one's or any of those type of one's, utter joke. Had one previously and they were limited to how much they pay out and even what they'd pay a mechanic per hour to do the work... Stay clear!!
I have one spare with 600 miles on it. It came off my 1 month old car last week. I live in Brighton so only 40mins away from SE London. You could collect or I could deliver (prob cheaper for you to collect).
How much you looking to pay? Will only sell if I think it's worth it!
PM me if you want.
