This car is very rare and its fast! It explodes past 90% of all other cars made, including many high performance sports cars. I think the BMW M5 is a fine vehicle, but if you want a reasonably priced alternative jet powered sedan...the E55 AMG is the only alternative. The Japanese only wish they could make anything comparible to this German autobahn jet plane on four wheels. If you want to operate this vehicle, be sure to have your pilot's license in order.
The roomy interior. Strong shifting automatic transmission. Its stealthy, clean lines and lack of any "over blown" pomp and circumstance, such as superfluous spoilers etc.
