Need fellow forum member insight / feedback - Had originally wanted an S85, but when I went on the demo ride all they had was a P85 to drive. Went back about a week later to drive the S85 (as that was the car I originally wanted) - so I ordered the S85 last Friday, and my confirmation date is April 10th. After "re-thinking" about the P85, I test drove the P85 again last night. As you might have guessed, I'm thinking about changing my order to the P85 - the acceleration was incredible - I know that it is clearly very different than the S85 from 0-30/60 and that from 40-80 is much less discernable. However, the acceleration from start is breathtaking. Cost difference is about $13k - (comparable equipment), but my concern is that if I go for the S85, will I be regretting it a year or two from now, and do the "should have done it" scenerio. I just don't know if the extra $13k is worth it for that "thrill" from a standing start, but everytime I think about that rocket-like launch it gives me a bigger "Tesla Grin". What do you think??
