Please read the linked article. Suggestions include 

apartments

office buildings

work out centers

But wait, vacancy rates in office buildings are still increasing, we do not ned more office buildings.

Condos, oh please. And Bally Fitness had to file for bankruptcy, hard to see people spending more money to work out. 

The idea that Chinese and other dealerships will vill the void seems far fetched.  With total sales still around 10 million, down from 14-16 M, there is really no need for more dealers, we probably need less. Indeed, the article mentions that GM will close another 1,000 dealers by next fall. 

So now we have empty shopping malls AND empty car dealerships.  These are a testament to the end of the consumer economy, ever adding debt for things we never needed in the first place. As PIMCO says, welcome to the New Normal.

The 1930s saw makers of luxury Duesenberg Auburn Cord go under as well as other small makers. 

Can GM survive with one million sales a year/  Perhaps on pickups and SUVS, probably not on Volts.
