I would probably trade in the TTS this summer or just after summer. If you are first on the list at ur lambo dealer then you should expect a car around May or June 2023 as they begin production in January. The price you get for your TTS this year I suspect is going to be much better than next year. Two reasons, one I anticipate we are heading into some sort of recession and second the 992.2 will likely be announced next year. Unless your state's tax is high Like us in ontario Canada (13% + 10% luxury tax) or BC (25% + 10% luxury tax), you might make more money selling it early vs your tax credit.
I have a TTS also as you know, i put a deposit down for a technica and i will be selling the TTS later around august/september. At least I can enjoy it for this summer haha
