Yes there is - if you look on e-bay(just search for KUGA) although I can't remmebr what the price was. You'll also find rubber floor mats for £25 and velor ones for £65 (both with £10 p+p).How much did the dealer charge you?
be careful with the rubber boot liner on ebay as there is one on their for £25 and its not actually designed specifically for the car - you have to cut it. Personally I've been using a non Ford OEM one for years and it fits ok in my Kuga with the end turned up at the back - gives me the option of having a bit extra protection when I drop the rear seats.
But if you are looking for a proper fitted boot liner make sure you get an OEM version and read the wording carefully.
picked up the bootmat yesterday and fitted it last night.
I thought that £60 was alot of money for it but it seems to be a plastic rigid liner that is coated with rubber. The fit is really good and pretty impressed with the quality.
Now with the rubber floor mats, boot liner and fabric protection I added the interior is protected from everything my son can throw at it - just need to find the time to remove all the mud that he got in the car prior to fitting the mats...
