Do a Paul Smart search. There is a lot posted here about them.
I own a Paul Smart. I will try to answer a few of your questions -
The tank has not spread but I live in North Carolina and most of our fuel is not blended with ethanol.
Fairings will not keep your tank from spreading.
The bike is not comfortable. There is a long reach to the handlebars but you should not have a problem doing that.
The engine has been around a long time. It's about as reliable as any engine can be.
I wouldn't keep mine outside but that's just me. It is a limited addition . . . but maybe not that limited.
The only ones that you will find will be used.
