part ex v trade in price - what's the difference?

[oop north]

Had buying disaster with new car for wife (seating position exacerbated her sciatica really badly after a week but not during test drive) so we need to trade in / p.ex against a different car only a couple of weeks after buying.

Got a What car valuation but am confused by it giving a trade in value and a part exchange price - I have no idea what the difference is (apart from £700 indicated). Can anyone enlighten me?

Is the trade in price actually "trade" price, with the p.ex figure reflecting that a dealer may give you a value above trade on buying another car from them? That would make sense but I would prefer not to make assumptions

We have that sorted thanks...

Thanks - have worked out the word "in" shouldn't be there, so the lower value is trade not trade in

I am aware that dealers have to make a profit and that margins are not huge. I let my wife do the negotiations as I am all too ready to fold if I like the car . We decided not to go for he car we looked at (a freelander instead of the Prius mistake - after two weeks of driving my D4 she is happy with the driving position - just wants something a bit smaller but seats not heated).
