For sedana and maybe coupes take apart you back deck and pop out the plastic cap to teh right of the 60/40 key latch. put in a bolt from a tripod and pop it all back into place, Now screw on your camcorder and go for a drive , it will be a steady shot and not shake around , like the old cops show, if you get it right you could even get it on the speedometer. good luck , let me know....
