The Logic of Multiple Vehicles

[Ginger]

So here's the question: is it cheaper and easier, maintenance, wear and tear, considered, to just own one vehicle

Yes. Unless you have a really long commute (40-50 miles) the math never works out in your favor for a 2nd vehicle.

Care to elaborate? I'm looking for a little more than yes/no.

Lets assume all vehicles are owned outright - sunk costs irrelevant.
