On the other hand, there is the Bugatti Veyron. Actually owned by VW, it is built in France and is a one-off automobile, essentially hand-built to the highest tolerances. It is neither ubiquitous (less than a 1000 have been built) nor inexpensive (estimated price of about $1,914,000 apiece).

It is like Google's database - huge (1000 horsepower), one-of-a-kind, and very fast. But it needs a lot of support.
One auto/database or the other is right, depending on your circumstances.
