As a European diesel driver, I'll throw in my three (euro)cents. Among the cons of a diesel car is not only the slightly higher price, but also slightly larger weight. On the other hand, today's hi-tech diesels (high injection pressure, commonrail, turbo) are as elastic and almost as quiet as gassers, yet need less fuel. This is because diesel fuel has more calories than gasoline, and because the engine itself is more efficient (I've seen something like 40% efficient, compared to 30% for gas engines).

As for hal9999's list of pros, diesel is cheaper than gas (point 7.), because it is less refinished (point 4.), so it's easier to produce than gasoline. This was the case until a few months ago. Now the prices are similar, because the need for diesel is much larger: not only are so many cars running on it, but the whole transport industry uses it (trucks, trains, ships). As an example I'll give you today's prices at a gas station nearby:
gasoline 95 octane: $1.30/liter, $4.94/USGallon
gasoline 98 octane: $1.39/liter, $5.29/USGallon
diesel fuel : $1.32/liter, $5.01/USGallon

And Americans are complaining about fuel prices...
