I'm getting the itch to buy/mount a video camera and would love to hear about others experience & recommendations. I have an 07 M Coupe. I'm not going to install a cage/rollbar, nor do I intend to drill holes in the body. I can go suction cup mount, perhaps could even mount it on inside of rear window. But, do auto-x / BMWCCA driving schools allow this? Suction mount works ok for my phone when using it to navigate, but sounds a bit dangerous to for on-track use. I'm leary of using the "removable" adhesive mounts on dash or paint. Then the matter of which model -- GoPro and Replay XD both look llke pretty capable units.
