What the heck is up with all the attitude from the administrators?I'd say it's in line on a trade deal.
Did you expect to lose less or something?
Of course, you could try looking it up yourself, as well as look over classified advertisements from dealers, Ebay, and so on.
Trade deals are just that though, trade. You can find retail numbers, but you aren't going to find a JLR dealer in your area, telling you the max trade in they'd give.
You're either happy with it or not.
Anyway, I think that trade-in value is in line in my opinion, I went car shopping a week ago due to the numerous issues on my 2016 and the local dealers on trade were offering $67 - $69K. Mine is a 2016 V8 dynamic loaded wth 22" wheels, 20K miles. I decided to not sell/trade because all of the vehicles I drove were missing something (cargo room, performance, comfort) in comparison to my range rover sport.
