Did a similar thing about 25 yrs. ago...had 12 cars, small apt...house hunting all the time. I mostly used the 32ft. units, and kept 2 cars in them, but, had a few singles that were 20ft. long. Climate control was not an option. About once a month, I would gather up my Wife and bro-in-law and transfer all the cars to the apt...work on them, and then drive them back...taking care NOT to be observed while placing car in a specific unit (and, if observed, moving it later to a spare unit, which would leave a would-be-thief with an empty). Another friend had 20 cars at same location...neither of us had any problems. Was VERY RELIEVED to get into house, and bring most under one roof(Porsches and Jags are MUCH smaller than Vipers are !!!).
Is the 15ft. length an INSIDE measurment?...I found the lengths to be overstated, causing me to move to 20ft.
The ILL. Club is a great bunch...you just MIGHT pick up an offer to store it for you as others read this post.
Good luck.
Until my wife moved back to join us in RI, I had no garage. If you can get climate controlled....go for it. I did not. The car did fine....but more importantly....I would have been better off!! LOL!! You'll need power for a battery tender. I did not have ppower....new battery time (sometimes I could not make it up EVERY weekend). I think it was a 10x15....maybe 10x20. I know that I put the car on the Sloan Kwikload and backed the whole rig in (now THAT took about 2 hours to get it in just right!!!). Had to take the fenders off the trailer and it just barely fit through the door. Once in it was good!
