At least you are not complaining like others on this board, and that is a good thing. Either poop or get off of the pot for Pete's sake. The suspense is killing me. Get you a sheet of paper and write down all of the reasons to buy or not to buy the GT3. Then get another sheet and write down all of the reasons to keep or not to keep the '87. Do what you want to do! Not necessarily the best or makes the most sense, but what you really want to do. If this is your bucket list and the last one on there, then go for the GT3. Life is too short. You will make the right decision!
