the hardest, BY FAR to remove and do will be the center console as it requires the removal of a bunch of things to get it out.
Its an easy job BUT you have to be patient and learn to use a heat gun properly. too much and you ruin the vinyl, too little and you will not get it stretched enough.
I just did my X with brushed titanium and it looks insanely nice.
BUT note that if you have ANY cracks in the wood trim now, the crack will be amplified when you put the vinyl wrap on, SO i'd suggest you sand down the cracks on the wood trim so the cracks do not push through the vinyl. See the second last and last photos above and notice the cracks in the black vinyl parts?
Also, get a proper vinyl applicator piece and be very choosey on which vinyl wrap you buy. the stuff I used, adn wrote about in my trim post, was the 3M new stuff and its the pigs tits!!!
