Yeah, you have to weigh out the differences: $8k (+ or -) off an '08 or MSRP (+ or -) on a '10. I am choosing the latter. I got a good price on a ordered '08, but then more details started leaking out. When I heard the "40% less moving parts" info, that closed the deal. My dealer was quite gracious in allowing me to back out of my order (no deposit). I think the fact that they didn't have any Cayman S's allocated for six months helped.
Yesterday, I went and looked @ my ordered car...very nice. But I know my next one will be nicer. But it will be another 8 months that I won't be driving a Cayman, and that is worth a lot, also.
