How much is the car worth?

03 plate black Porsche Boxster 3.2S
Full Dealer Service History
good condition

Sticking it on autotrader for a friend. What's the going rate for these things? The prices on there seem to fluctuate quite a bit and I'm not sure what to put it in at.

Thanks.

Seems a bit low comparing it to all the other models. Even the lowest priced model is a good bit more than that.

I thought whatcar always gave low figures?
