Iain, Ive taken the step to sell my dci privately, since the difference between trade and private value is quite significant. It isnt that much hassle selling privately.
Much of it depends on how sought after your car is, and I personally think the dci would be quite sought after since it offers better performance and mpg than many of its petrol siblings.
Autotrader costs £15 for 2weeks online or £43 for 3wks online and 2wks in the mag. I tested the water online first but have now opted to go the full monty.

Dealers near me are offering piss poor trade in values at the mo, and not just for Renaults but also my g/fs 2 1/2yr old Ibiza ( £3500 and its only done 10k!)
Trouble for dealers now is that they make their money on finance mainly since new cars are so cheap, and so used cars offer little opportunity to make some cash as most buyers still go for new cars. Ever wondered why most dealerships dont tend to have used cars over 2yrs old on their forrecourts?
