So I've recently walked into an opportunity to trade in my S85 with 16,000 miles for a P85 with 29,000 miles... Pretty much at an even exchange $ wise. The question is... Do I do it? Is it really worth it? I don't want to make the trade, hit the pedal and be like, that's it? I really really want the power factor.... But there's also a sentimental factor.. my current S was my father's car and I inherited last year when he passed away. Just wondering what others here would do.
