I went back and forth on what tool kit to put into the car. BMW does sell some decent tool kits (see part number 82292151462, for example) but their kit isn’t very comprehensive for what you get. Instead, I bought a Proxxon (German made) tool kit. I had bought Proxxon before from Ride West BMW Motorcycles when we lived in Seattle. Really nice stuff, on par with Facom or Snap-On. This time, bought from Amazon. The kit is kit number “Proxxon 23080 36 Piece Socket Set with 1/4 inch Square Drive” and I paid $64.60 shipped for it from Germany. The kit doesn’t have everything… I’d like to add a pair of larger pliars (bigger than the Leatherman ones already in the car) and also an adjustable wrench, but it’s a good start. Fits nicely into the area on the left side of the car near the rear tail light.
Total cost of this mod = $64.60
Total investment in vehicle to date = $4186.00
