There are plenty of DIY vids on you tube showing how to vinyl wrap trims, as well as DIY posts showing how to remove the trims. I did my Merc last year and it was pretty damn easy. If you can wrap a Christmas present and work a hair drier you'll find it simple. Just set aside plenty of time and don't rush.
