The idle actually sounds very cool, but the low to mid-throttle passes sound less than compelling. 8 cylinders sound awesome (with the right exhaust) all the time, 12 cylinders sound wicked at high revs...I think 10 cylinders fit in the mid to high rev or idle category.
Very nice car though. I'm toying around with the idea of getting something like this or a GT 500 for my next daily driver. No kids, most everything is paid off, the GT is about to be a track only monster, time to reward meself...again.
