Volkswagen Phaeton
The Phaeton is one of the most confusing luxury cars ever made. Part of the reason was the intensive process Volkswagen put into production. Every Phaeton model was hand-built in a special factory designed for this car. The level of detail that went into the Phaeton is part of the reason why it is one of the best luxury cars ever made (via Top Gear).

The emphasis on quality made the Phaeton drive amazingly well and the off-the-line performance was excellent. When you get behind the wheel of the Phaeton, you know that you are in for something special. The luxury engineering that went into the Phaeton made it one of the best-used luxury cars on the market.
