i had one of them in my bmw. i payed £1700 for it about 18 months ago and i sold it about 6 weeks ago for £650 as soon as i put it up for sale i had loads of interest and it sold straight away. if u look in max power and revs u can pick a new one up for £1100! its a proper bit of kit and has touch srceen and about a millon other things it will do. that bidding will go to £500 no probs i reckon!
