Real estate growth industry: Store thousands of unsold cars on your vacant land

There's a giant pile-up down at the Port of Los Angeles. No, not the usual oops between an 18-wheeler and a passenger car on the 710 corridor. It's a pile-up of unsold vehicles.

Thousands of unsold import cars -- everything from SUVs to hybrids, are sitting idle, waiting for dealerships across the country to sell their backlog and replenish. Trouble is, in the worst car market in a generation, nothing's selling. So the car companies have leased vacant land at the Port of Los Angeles (the biggest port in the country) for use as a massive parking lot.

Now it's running out of space. Toyota and Mercedes have quickly leased more acreage, but Nissan couldn't arrange it and had to find parking lot space elsewhere.
