253

The hyperexpensive (one million euros and then some) Bugatti Veyron 16.4, once you set it for top-speed mode (which you do before setting out on a speed run), can do, and has done, 253 miles per hour.

The Carnival of the Vanities is slower — one per week these days — but there have been 253 of them so far. Next year should mark #300 — which is also the total planned production run for the Veyron.
