If depreciation is a major concern (you plan to re-sell it in the relative near term, or simply don't wish to feel like you wasted money because the better part of 100k is not meaningless to you), then you may want to either wait, or consider an older (3+ years) model. If you are patient and do your research, there are some real gems out there in immaculate condition with great maintenance history (of course there is also opportunity cost to consider with all the leg work it will take). I only paid about $20k for my 2004 and it is spotless (not even one bubble in the laminates or anything) and had detailed records for every service performed (and I am doing the same myself, documenting everything I do so I know what the real cost is if I choose to look back in at any time). I am well aware of the fact that there will still be significant cost of ownership, but with the money I save by not getting a new one, I figure I will probably come out ahead (especially since I am pretty handy and perform quite a bit more work myself than most people would). In a decade or so I may think about an upgrade.
Of course, I do lack some pretty cool features which the newer models have, but it still fundamentally blows away a (slightly newer) honda/toyota which I could have bought for similar prices.
