The beating the .1 will take due to the .2 engine makes me worry about what Porsche has in store next. Best advice is always sell prior to the next one’s specs are known.  The time to sell the .1 was about 16 months ago. 

I've not had my .1 that long.  I bought in after prices had started downward.  My car would be one of few CPO'd available, and looking at what they are going for now, the price for my car hasn't moved at all.  Of course the dealer will offer quite a bit less on trade as they love to do.

I'm not worried about the engine so much, it has a 10 year / unlimited mile warranty on it as negotiated by US owners after the whole fire fiasco.

I'll see what they say, my guess is they'll want too much so may end up being an easy decision.  But the want is strong.
