S80 D5 Executive
 

I have a 2012 S80 D5 Executive , I`m thinking of selling ,it`s done 138000 miles but drives like new , just been m.o.td fsh in pearl black with cream interior excellent condition inside and out , massaging seats , adaptive cruise , lane depart, front and rear heated seats front and rear parking sensors sunroof and much more , whats it worth ?

Have a look on eBay or Autotrader for equivalent sales listings.
On eBay you can view completed listings to see what they actually sell for as opposed to what the asking price is.

For a 2012 car the various online car valuation sites will give a feel of its value to the trade (webuyanycar etc), generally add £800 or so for a private sale, and expect forecourt prices to be up to £2000 more.

I reckon £8000

I reckoned wrong , and so do the dealers £6000 buys it if anyone`s interested
