I have the JLR centre armrest cooler / warmer available
https://store.landrover.com/cool-box.html

I bought it as new last year but our trip was cancelled. I've used it in the boot to keep water cool but it's been in the garage for the last 6 months.

it has some superficial marks from life but these arent visible from any distance.

£110 collected or i can deliver to most Scottish cities.
