For that reason I copied Groucho's setup and bought Cannon HV20 which uses the mini DV tape...Works perfect.
I bolt this down hard between the seats and use the wide angled security camera as a remote input.
You could in theory isolate the camcorder in foam and then use a remote input (if that cam will accept an analogue input). If you isolate it I'm not sure it won't shake too much to get non jerky video.
Search on Groucho to see the wide angled cam..Works great for in cockpit stuff see

For less than $100 it might be a better option than a new cam.
