Car storage

Any suggestions for car storage relatively near Philip-Goldson Airport? 
The situation is that I am coming frequently, and the roughly $100US/day car rental is killing me.  I'd like to buy a vehicle and keep it in secure storage somewhere near the airport.  I've heard about Edgar's, but I don't know if this is still in existence.
Any thoughts on this are appreciated.

Global Village Hotel right on the Northern Highway is where I always park when I fly out. I have only used them for vacation-length trips of a week or two, but if you talk to the nice owner in person, he might make you a good deal for longer-term storage. Airport pickup and delivery included, of course.
