I have a pair of unused Jaguar XK seats in black as per the attached photos. 

Any idea what these may be worth or the best place to sell these?

Hi

Put them on ebay, by far has the widest audience,

just look on there and see what other seats are selling for, then adjust because there unused

do you know what year they are, as the drivers seat on some will be canbus controlled, might want to include pics of any modules underneath them and if there heated or not, will make them worth more

cheers
