Stop in for a cup of coffee

Need to find me a good idea on protecting my Scamp when I travel to Pittsburgh so I can stay at a motel on the way and not worry about getting my car stolen.
I can when parked turn the front tire all the way to the left or right and locking the steering wheel. I have a hidden battery shut off that takes a key. Hood latch is a button under the dash.
I can easily remove the steering wheel. My car alarm bit the dust so need to replace it.
I like Hoppy's idea of hooking a coil to the car body but not sure how to do that and the liabilities on shocking some innocent person that tries to lift the car cover for a peek at my car even if I put a sign on it stating "DO NOT TOUCH"
I have insurance on it but not wanting to collect it if it is stolen I prefer to keep my car.
Sleep in it… 1911 under your pillow
