HI Paul,

Prices vary dramatically for Qashqais of that age, depending on engine and specification. The cheapest, with high mileages, are up for sale at around €15,000, while the most expensive are priced at over €22,000. The trade-in price will be a couple of grand less than those advertised prices, obviously, and it will also depend on how badly the dealer a) wants your car and b) wants to sell you their car. It's not a scientific matter at all...
