I've owned my 2014 528i x-drive for a few months now. As my father-in-law is a retired Ford Exec, I've been driving American for decades. I can safely say that the BMW is easily the finest ride I've owned. My last car was a 2012 Mustang GT, which boasted the ungodly HP, but little else that compared to the 5-series. I enjoyed adding a few cosmetic and performance enhancements to that car (well, I had FMR install them). However, the Bimmer seems to be untouchable ! I wanted to add options that weren't installed at the factory with no success. So I ask you people here: What sort of mods can I add to this (admittedly perfect) car ? Within reason, of course, I still have a few years left on the mortgage....
