To me, it’s pretty amazing that the Quattro hasn’t really received the attention of the E30 M3. The Quattro beat the M3 to the market by 6 years with its squared, chunky boxflare stance. It was all-wheel drive, turbocharged and cutting edge. It revolutionized the World Rally Championship and firmly cemented Audi in the halls of motorsports and enthusiasts minds. The offbeat 5-cylinder hanging in front of the wheels seemed an odd choice, but Audi has returned with an updated version of that power plant in some of its newer models, and the sound and performance is no less memorable than it was in the original. Indeed, in terms of what a single car did for a brand, the Quattro was much more influential for Audi than the E30 M3 was for BMW in my mind. Yet today, if you want to get a great condition E30 M3 with under 100,000 miles you’re looking at over $50,000 to play; if you want to get into the original Quattro, nice examples can be had for half that amount:
