The 997.2 GT3 RS is the last manual RS produced. That’s says a lot. Before I bought mine I was also on the fence between this and the new 991.2 GT3 manual. The RS moniker is only given to the most special Porsche’s. It’s more exclusive than any of the new offering. That’s what put it over the top for me compared to the 991.2 GT3. And as you can see now, the GT3 prices are already normalizing. If you must sell then I would not sell for anything less than 170k. But I’d keep it and watch it bring in more $ in a few years. It’s one of the greatest drivers of the modern era.
