M-sport kit in after market + painting was to much for me so I didn't do it.
In stead I wanted to get the stock bumpers cleaned and painted like you already seen here. One difference, I don't haver any kit (s-line, x-line).
Cheapest place was also the place a friend advised me. 800 € and 3 day's of work they told me. This work included cleaning the front- and rear bumper, the sides and the 4 wheel arches. Painting all this and also the side mirrors.
I did only pay the given price but I did miss my car for a week. Getting out the structure was a lot of work. Other car shops didn't even wanted to start at it or where asking like 1500-4000 €.

I'm happy with the result.
(Still need to order black grill and window strips to match.)
