A general metric I've read is that the price premium for buying a diesel-powered vehicle will be recouped in approximately 4 to 5 years. This takes into account the improved fuel economy, and also that diesel vehicles tend to depreciate more slowly than their gas counterparts.
However, I can tell you that there's an emotional component that you can't put a price tag on. Having a diesel engine is fun, and radically changes the car's overall character. Whether it's the low-end torque, or the different sound the engine makes, or that you can pull right up to the diesel pump when all the gas pumps are being used at the gas station, or being able to drive 600 miles between fill-ups, owning a diesel-powered car makes for an interesting experience.
As long as that diesel car is reliable, of course.
