i had LLumar ppf on my 458 and it was good. self heals with warm water or in the sun. It is thin though so if you're driving through a salty winter or a regular highway commute it isn't going to hold up like the thick xpel stuff. I had llumar on my 335i front bumper as well and it was chewed up after one winter and had holes. xpel i've heard sort of diminished paint appearance though due to it being a thicker film.

also don't tell them you have an M8. tell them its a 2013 640i or something. if they change price when you show up ask them whats so different applying ppf to either. many shops price gouge if they think you got money.
