Working at a software company (i.e. around geeks with disposable income) and living in the yuppie part of downtown (i.e. around yuppies with disposable income) I see a lot of people driving around in expensive cars that have a popular brand name but not the quality associated with that brand. Such people would have gotten more value for their money by buying equivalently priced cars from other manufacturers but decided that riding around in a big name brand was better. Examples of such vehicles include the

1. Jaguar X-Type

2. Hummer H2

Some others come to mind but I won't mention so as not to risk offending people I know. I always shake my head when I see people driving around in these cars.
