no question for me, though I haven't driven the Cayman GTS, I'd keep saving my money until I could get a GT3... i felt that way when i drove it, and Justin's thoughts on both convince me I'd rather have that sheer lunacy of the GT3 in my life... I probably wouldn't be driving it every day, and would drive a Cayman more often, but the GT3 is, as Justin says, is 'beautifully haywire' and oh so special. and to get this thing on a track, oh damn, the noises it makes...
