Sorry..couldn't resist. It's not all about the name. Every manufacturer puts out a lemon or two.
Regarding the porsche v sti...he posted he beat the guy. Regardless of anyone's questions, thats what was posted. We weren't there so any winging or comparisons are moot.
I personally stomped all over a stock Boxter (non S) the first year they came out in my stock WRX (at the time). Frumaroll and fromadig. Didn't matter.
However, I recently had the opportunity to drive one, and lets just say the handling is sublime. MUCH better than any stock subaru platform...spec C, RA...whatever (yes, I've driven them also). Didn't or doesn't the boxter currently hold R&T or C&D slalom record? I usually chuckle at their 1/4 mile times, as they obviously are in need of some lessons, but their handling tests are usually pretty accurate.
