The roadster is a NVH nightmare though. Any idiot can build a sports car, but it is a real challenge to build a luxury vehicle. Luxury cars and economy cars are both an order of magnitude harder than sports cars from an engineering perspective. People will forgive rattles, wind noise, and steering nibble in a $100k+ sports car, but not in a $60k luxury car. The real test will be if they can sell the product to buyers who aren't already sold on the concept.
