I have a Tonneau Cover for a +4 available.
It fits my 2017 car with an easy up hood.
Its Green, made of ever flex vinyl, single zip with no head rest pockets. I bought it with the intention of recolouring it black, but have decided as I really want a black 3 zip version & head rest pockets I would be better off reselling & buying new.
If you are anywhere near Bedfordshire I would be happy to deliver, see if it fits etc.
Happy to post photos when I've remembered how.
Am looking for £225 including insured UK postage.
I think I've got a complete set of the body fixings needed if your car hasn't already got them - just need to check that.
