It is by far, the most sacred place for a BMW M fan. We’re talking about the BMW M Division’s underground facility where the company stores copies of all the production cars and prototypes it has ever built, including a variety of never before seen in public vehicles. In a surprising but much welcomed move, the German automaker recently opened the doors of the special M garage to the members of the press and select enthusiasts revealing an array of models that most had only heard about.

We already brought you a video of the wild M8 Coupe with the 580-horsepower V12 engine that was eventually used on the McLaren F1, but now we have several videos showcasing the entire lineup of M cars.

These include the E46 M3 Touring (BMW for station wagon), the E36 M3 Compact powered by the same 321HP straight-six from the M3 Coupe of the time, the E34 M5 Cabriolet with open-top seating for four, an M3 powered E30 ute and possibly the strangest creation yet, the so called Ur-Roadster. The latter is said to have been developed after the Z1 with power being delivered by the E30 M3’s 2.3-liter four-cylinder engine.

Check out all of the cars in the videos below.
