The E30-generation BMW 3-Series is one of the hottest affordable classics out there right now. Why not kick back and watch this cool documentary about how it came to be?

This half-hour German-language doc covers everything you could possibly want to know about how the E30 was born. Though there may be a language barrier, there are still tons of footage, animations, diagrams, and visual explainers that give the viewer a good idea of what's going on.

The video highlights just how much tech was involved in the E30's development. The car's design was optimized for aerodynamics using computer processing and wind tunnel testing. It also shows how much automation was involved, even back in the early Eighties.

If you have 30 minutes to kill, we recommend it. Especially if you're into old German metal.
