> A car's ownership costs are dominated by fuel and depreciation. You're probably going to come out ahead of those fixed costs on gasoline savings alone.

Depends how much you drive. If you don't drive much to start, and then having two vehicles cuts that in half, your effectively-fixed costs go up - e.g. you start having to replace your tires because the rubber is getting too old long before the tread wears out, insurance doesn't scale down linearly for low-mileage drivers, etc.
