use series 3 as a bargaining chip... mention something along the lines of 'well i know in a month or 2 a new series will be coming out, pushing down the value of this car, so think u can work that into it?' or some such, u improvise
but yeah, sounds good, leather and manual will hold its value better than standard vrx's (as seen in vrx's now) so that combo should be a winner down the track
