I can't get the tail-gate open on the car I just bought from CA. It had big knobby tires and green camo wrap, you might have seen it advertised, any way I bought it and now it is at my house with new tires that don't rub, but can't get the rear tail-gate open. It is a 2009 cabriolet convertible. I followed the manel, went on line, but no help. Before I take a grinder to it, I slowed down and figured who most to help but all the experts at this forum. !!!! HELP me PLEASE !
