However that’s exactly what a lucky few trainees did when BMW tasked them to make their design study a reality. Choosing the firm’s Mini Paceman as the donor car, the talented apprentices transformed the vehicle into a rugged two-door pick-up – a long way from the original motor’s sleek coupe origins.
