Where to sell a 730d Sport with 18mts BMW warranty ?

[phib]

I am thinking about selling my 57 plate 730d M-Sport, I previously had a 535d that seemed to attract every time waster known to man when I sold it and I really don't want to go through that again.

I am thinking autotrader / pistonheads but is there anywhere specific that might be better ?

The main reason I don't want to part ex is the car has full bmw warranty until June 2012 and I am sure that must slightly set it apart from the usual dross on autotrader ?

Any advice welcome
