Back in the E34 era, BMW had plans to build the convertible version of the popular M5 model. Engineers from Motorsport had indeed developed such a vehicle, with two lengthened front doors and four seats, which was very close to production.
All the preparations were made: the price was set at 50,000 GBP and there was even a space booked for the Geneva motor show. Unfortunately, one week before its expected debut, BMW backed out. Why? Because they believed its release would have increased the demand for non-M5 Series convertibles, making the 3 Series sales.
The crew at TeamSpeed.com released some photos of what the E34 M5 Convertible might have looked like, had it gone into production ( PS: The ZS stands for BMW Individual ).
