I myself have not done this ,but I have a friend that has a black 05 vette.We were all out on the river one day boat riding and enjoying several cans of loudmouth soup,before we left the boat landing ,my friend just laid his top back on the car without latching it.Upon our return,he takes off and the top took flight at about 45 mph,no one was behind him luckily,but the top took a good beating.It had cracks in it and was scatched and gouged beyond belief and repair.So, my freind finds another top from a guy in Texas,he had a black 05 that was wrecked and sold him the top for 900 bucks.Now,about two weeks or so later he calls me and told me he forgot to latch his top AGAIN,it took flight at about 30-35 mph.The damage wasn't as bad as the first,no cars behind him and the top went off into the grass so it saved it ,somewhat, from total destruction.He has yet to get that one painted/touched up.
I have put my top on and for some reason(probably because I set it on there crooked in the first place) the pin didn't go into the hole in the back ,but the top still latches,it rattles instantly and that is when I realize what the problem is.This has happenend to me three times ,but I am now in the habit of taking the few extra seconds to double check everything before take off,after I latch it I even pull up and down on it a little bit to make sure.I concur ,there should be some sort of light or warning signal indicating that the top is not secured properly.
For anyone that is looking,My friend did have good luck locating tops for sale on ebay,you may luck up like he did and find the same color to avoid having it painted,just a thought.
