BMW Blog took some amazing photos of the iconic BMW E12 M535i at the test drive event that BMW held for select automotive journalists.
The M535i was introduced as a sporty version of the regular 535i. It is the M-Technic suspension, wheels and body panels not found on the standard 535i that makes this car special. It was the only official BMW Motorsport-developed version of the E12 5 Series and the only E12 model powered by the 3.5-liter M30 inline-six from the E23 735i and E24 635CSi. As a cherry on top, it also has a BMW Motorsport-tuned chassis and several unique cosmetic items.
