I doubt the inspector who does the end of lease check in cares but I have a wife who does, she had a conniption fit when I told her I was going to hide the power cable for the dash cam in the liner. I did it without telling her, will be interesting to see if she notices.
The hood to fender gap is pretty tight, I might use trunk mounts since it has a nice lip by the windshield.
I don't have a center dome light so fishing the coax might be a bugger.
I might be able to use mag mounts, the trailing edge of the front door and leading edge of the rear meet over a channel in the frame, so the coax might not get pinched as much as some of the rental vehicles I've had the mount in.
