What in god's name are you blabbering on about?
BMW and Mercedes (for example) make, on the whole, higher quality vehicles than Ford and Honda (for example). This extra quality comes at a price.
See also: Apple iPhone versus something like a Blackberry Bold. Saying the iPhone is overpriced and for snobs is a matter of opinion. It doesn't mean it isn't a better overall product.
Higher quality in what way though? An iPhone doesn't cost much more than a Blackberry to build, how they price the item is another matter entirely, and one thing for sure is that Apple products are massively over priced.
Pricing is usually down to the product itself and the brand. The likes of BMW and Mercedes can charge much more for their products because of their brand, they are perceived as a premium brand and people are willing to pay more for the brand. That does not make their products superior to other cheaper ones.
I would agree that a lot of the products by the likes of Audi, Merc and BMW are over priced, you compare a base spec Merc C Class to say a Ford Mondeo, and what you get for your money is a hug difference, I would easily have the Mondeo, as I don't see the Merc superior in anyway apart from putting your keys on the table in the pub to show people how "successful" you are.
Even if you move down a scale and onto VW who are just a standard mainstream manufacturer their products tend to be more expensive then some of their rival brands from other nations, all because of the badge it has on the front that allows it to charge a premium for its products, whists in reality the product is not superior than some of its rivals.
Even if you move up the scales and onto the performance models, they can fall short, you just need to compare the Nissan GT-R to some of its German competitors, and the latter starts to look over priced.
