This basic but the most common slogan can be observed in automotive industry also. Ferrari, Lamborghini, BMW M Series, Mercedes AMG Models, Audi RS Models and many more. They have the same principle like a jean, sex sells. Very few people are buying these cars for their handling or to utilize their enormous amount of power. They find an attractive point and they buy it. Like people buy jeans. Especially jeans like Diesel! They have chance to buy Paul Smith jean but that is not associated with Sex Sells! That's just a jean. People can buy a more normal car for the same price with they want to buy an aggressive one!
