NPN Classics Born from love for electronics & classic BMWs. DIY parts, repairs & full cluster restorations. Built by an enthusiast, for enthusiasts.
Old is Gold!

BMW E30 Hobby and Electronics Engineering experiences lead me to some small Projects and Solutions for building my own e30. Today I'm able to offer my products to the BMW Classics community as well.
