If you want to show your identity, you can buy Audi A8 3.0 or Mercedes-Benz 320. The performance of these cars is really good, but the cost of maintaining them is high, and then driving in urban areas feels that the body is not flexible.
A friend of mine bought A4 1.8 because A8 3.0 was not flexible. Now A8 3.0 is mainly used for long-distance driving.
