I did one about 10 days ago,it was £1600 odd plus Vat from LR - that was the retail price,I paid alot less with trade discount on a stock order over 3 days.Be worth asking what you can get knocked off.Its not a bad job to fit it either if you can get access to a ramp.Fire a couple of cans of Dr Tranny Cooler cleaner through the cooler,just to be sure.
At a price as low as that its well worth considering,esp as it gives a proper LR warranty at any main dealer.
