I installed my own, it was pretty easy. Follow the directions to get the assembly sequence down. I put down masking tape on the trunk lid. Positioned the rack with the feet washers in place and checked it about 20 times, taped the entire thing down and checked it another 2 or three times, marked it and drilled it. Like someone else said, if you don't have the spoiler, mount the rack within about 1/4" of the front of the trunk. I have the spoiler and that's about where it ended up. I also found myself checking several angles on the rack, most importantly to keep it centered on the trunk is to line it up with the key hole (trunk and ignition). Just take your time.
