I'm driving myself crazy waffling back and forth. I have always traded cars, even after a year, when a more powerful version of a car I like comes out. It's an irrational obsession, I admit.
However, the Dream Edition is just so damned good as a driver's car on public roads in every dimension -- power, handling, comfort -- that this is the first time I might be able to say no. I couldn't make use of the extra power, and the blend of compliance and precision is so good in the Dream that I really worry about moving to a stiffer suspension setup that will probably only pay dividends at the track to which I will never take the car. And, although I think the blue color is really snazzy, I just can't get my head around the Mojave interior and sport seats. (I have never owned a car in which so many people climb in and start raving about how gorgeous the interior is, including the different colors of the front and back seats and the eucalyptus wood, both of which I have really come to love in the Santa Monica.)
I understand the want to upgrade your car regularly - I'm similar and treat it as a hobby. But upgrading to the Sapphire is not worth the $80k difference from the DE, especially considering you'd give up a few features, like the traditional luxury seats, suspension, and an interior with more personality.
I prefer the luxury features and styling, so the Sapphire almost feels like a downgrade to me. And with a $110k difference from my GT, its a HELL no.
For someone who values performance at all costs though, more power to ya, just don't forget the GT-P exists.
