Price Difference To Buy Used 4X4 In The Summer

[bamberger]

I will be needing to buy a 4x4 car that can tow 2.5 tonnes in the next few months. There aren't a huge number of cars that can do that and I've narrowed the choice down to a Shogun, Land Cruiser and Discovery 3. If a dealer has a four year old one on the forecourt now for £20000, what price might a similar four year old one be in July when the winter is over? Would it perhaps be £17000 or might the difference only be £500?
I know its not an exact science but as I don't need to buy today , I am wondering when the best time might be.
Thanks
