Expensive? Naaah. Second fastest care for the price range, I think. I'm sure M5 will come in and tell us. Please? But as I was describing to my parents earlier, Subaru's aren't refined. The shifter is clunky, there are loud noises, more rattles and such. I do notice it, but none of it bothers me. It just may set a few people off.
I think an STi would murder the V6 and GT Mustangs, but they can just wave bye bye to the supercharged Cobra. That thing is a hoss, as far as straight lines go. They're in the same class according to SCCA, which sounds about right. Mustangs don't seem to have the best handling capabilities and I imagine that's where the STi makes up for being down on power.
Heavily modified WRXs are running pretty quick straight lines. There are videos of a WRX beating a Z06 by a car length (went to about 110mph). There is also another guy running 10.9s in his WRX. But this is also with a stock transmission, and legally too.
PS. It's a bit off topic, but I was suprised to learn the 350Z were so slow!!! They seem like such a monster of a car, but they're horrid in a straight line. 14.7s or so for a stock 350?! Wow, even the WRX is rated faster, and I thought I was in a much slower car. It's probably faster around a course, but I was suprised how slow it was in the straight line.
PS's PS. I just looked at the last autocross and even though I'm just a novice, and only had my car for a month and never raced it before, I was only two tenths behind the 350Z that was there! He must suck just as bad as I do.
Average driver should be able to hit low 14s.
