My favourite Bugatti is the Type 55 Roadster but why are they soooo expensive?
Sadly a result of two factors:
1. Lots of other people agree with you
2. They only made 38 of them
Since we can't travel back in time and make more of them, the only answer is to start a world-wide movement to persuade everyone else that they are actually rubbish so that no-one will want one apart from you. Then you'll be able to buy them all at a knock-down price!
