Never been a big fan of the Boxster....if I was going to get anything from Stuttgart, it would be a 911, especially now since the bloody little thing is almost $100K. Like NoTo said though, the Toybaru/Subiyota is a hell of a deal a 1/4 of the cost.
The Toyobaru is a great deal, true, but it's a bit disappointing to drive (many will disagree with me on this, but the MX-5 is better feeling if a bit sloppy, and no more than a tenth or so slower). The Boxster, on the other hand, feels worthy of the hype, if perhaps not the price-tag.
Incidentally, the last base 911 Cabrio (manual) I drove stickered out in the $150K range, with the same options as the S. I like the 991 (not love, but like), but the Boxster feels more of a sports-car.
Of course, for that kind of money I'd have a Flyin' Miata 'charged MX-5, spend ~$10K at Skip Barber learning how to drive the darn thing and have enough left over to pay down a sizable chunk of my mortgage.
