I am about finished with my DIY build-out of a PM. I've never figured what I didn't get for the $$$ I saved over Sprinter or Transit. What I did get include wider body, straighter sides, galvanized high-quality steel body not prone to rust, amazing stability in crosswinds, FWD which translates to sweet handling and lower floor which translates to easier ingress/exit and lower overall height. What am I missing?
