Somewhere secure to park car/trailer near Mulhouse/Basel

[fistenburger]

I'm off to the Alps this summer with the Caterham to enjoy a long weekend of laying rubber over the many Alpine passes in France, Switzerland and Italy.
I cannot be bothered with driving the Caterham all the way from Bristol to the Alps as i'll likely get a raging headache, armache, legache etc etc from the 7+ hours on the Autoroute. I can't really take any longer than a day there and a day to get back as I have limited time off.

So... I want to tow the Caterham on a trailer. I'm struggling finding secure parking for a few days so I can leave the tow car and trailer and still find it all there when I get back after wearing the caterham's tyres out.

Any recommendations in the near(ish) area?
