Our X's are twins. Sophisto Gray X lines. We both went 20's pretty quickly as well. I recommend the Ebay ABS fender flares. Cheap and fit 95% of factory. Very hard to tell unless you are an enthusiast up close they aren't OE. Yours is younger, cleaner, and lower mileage. Makes me a little envious. Ours gets better gas mileage though.
Funny I was just looking up upgraded steering wheels too. We had a loaner m sport 5 series while the dealer was doing our injectors and the wheel felt soooo good. I think I am going to invest in a nice leather wrap for ours. I'd like to switch to M sport, but with this diesel I'm trying to avoid m sport touches for fear of scope creep leading to full on conversion. Don't want to do that on this one. lol
