Have you ever driven a Mercedes Benz or a BMW? Did it feel luxurious? If you answered yes to both of those questions then you are kidding yourself and you have never experienced a true luxury car. Luxury and Exclusivity go hand and hand. You can't have one without the other. Let's use the numbers to put this all into perspective.
Nearly 300,000 BMWs and nearly 300,000 Mercedes Benz autos were sold in 2007. With figures that high it's hard to call those vehicles exclusive. Royce sold 1000 units. Lamborghini sold 2400 cars. Aston Martin sold nearly 8000 units. Bentley sold 10,000 units. Compare 300,000 units to 10,000 units, and then spell out which company sounds more exclusive? Before we go any farther, it should be noted that an automaker's sales figures should be of statistical significance to their respective class in order to bring a comparison. All companies which are being stated for the purpose of this expose sell enough vehicles in their class to make them statistically significant.
Some people will claim that Mercedes Benz sells the McLaren SLR super sports car and the Maybach luxury sedan. At $ 450,000 and $ 480,000 both car are could be touted as exclusive and luxurious. I guess you could consider that a proper argument if both of those cars weren't vastly inferior to other cars in their respective classes. Inferior, yes both cars are vastly inferior to other cars which are sold in the same class as they are. If they were superior then they would match or beat their respective competitors in sales.
