> Most major airports charge very high parking fees. LAX charges $1000 for the first day, and that goes up to $5000 a day on day four.

That seems pretty cheap to me actually. A random Google search suggests that an airplane costs at least $100MM, so $5k per day is 0.005% of the airplane's value.

Scaled down proportionally to a $100k car, that's only $5 per day, and considering that many parking lots charge $5 per hour, that seems like a pretty good deal.
