Is it really worth the extra $3k to buy the Grand Touring or what?? Apart from the BOSE speakers, Hid kit, leather seats, rain-sensing wipers, is it something I should consider buying? Ive already made up my mind to get the MS3, and hopefully in a month's time i'll have one, but ive been looking at sports cause they are in the $22k range, and the GT's i've seen start at $24k and go up to $25...What are your opinions - I'd like to hear from guys w/ Sports (whether u regret it or not) and guys with GT's.../chris
