Hope you get it sorted , I'm afraid the only option is to park at the far corners of supermarket car parks
I wouldn't park mine where you had parked yours ! , however you should be able to park in any space and expect your
Ride to be in the same condition when you come back.
It's so annoying , you thought about investing in front and rear Cameras ? You would have caught the culprit yourself
