Oh, there's enough space, just not in a garage or even the carport. And for a year-round all-weather car, it should live outside anyway. It's no fun to have ice, snow, and slush, dripping off in the garage. Also, it promotes corrosion to thaw it out in a garage.
Realistically I could/should sell the Audi Q5 I just bought, that'd free up a space in the carport. But then, so much for having a little all-weather beater that also gets good mileage.
And I'm not convinced that a Durango would be a much better winter car than the Trackhawk was. I would hope they have better ground clearance, but haven't checked.
