I was going to go for these covers:
(it won't let me post the link because I've made less than 12 posts)
my seats are horribly stained (watermarks) and despite being valeted several times, the stains won't shift. I'm not keen on the grey seats either.
I like that armrest, where is that from?
armrest was bought from eBay (see link above)
just found it on the same site as the car covers you posted at a sale price

, on post 30 i put up the way i did mine, i know some other people have gone another route by removing the radio and storage tray but i dont know how that would work 
Sounds silly but give it a pull. If that doesnt work, pull it harder.
