God i love how ugly it sounds. It reminds of porsche engines at low rpm. But once they start to open up has this crazy gurgle angry sound. Nasty sounding engine. I do like this car a lot you've done an awesome job. You bought a grey one before that style was a thing. Now everyone running primer lookin or grey cars. That offset blue. But to the n55 I hope more mods are made especially for the 640. Just noticed at the end 2015 and lower 640i pwg? I though f series 14 and up were electronic.
