I am about to lease a new car for the very first time and am a bit unsure about whether to bother buying a bootliner for it or not.

It is only a 2 year lease, so I don't want to waste £140 on a bootliner I will probably never use after the car goes back, but we do have dogs that infrequently travel in the boot of the car. The dogs are big, very hairy and often travel with a degree of wet/mud/general stinkyness attached, so am I likely to be charged for steam cleaning/valeting the boot on return, or would that be considered as fair wear and tear for the boot area of a car?

If I am going to be charged for a steam clean anyway, I may as well suck up the bootliner cost instead, but just wondered what other people do who are in a similar position.

TIA
