 Due to the lack of marketing, an 06 Grand Touring is a terrific bargain.  Mine includes nav, roof and autodim mirror.  I like my Mazda better than a BMW 530 I recently drove.  The Mazda is very refined, smooth and ultra quiet.  The AWD make it even more of a bargain, brakes are fantastic and traffic "darting" while not condoned is very easy.  The car handles like a dream and has almost no body roll at all in the twisties.  Insurance is cheaper than you'd expect!  The nav is a waste - DON'T DO IT!  You can't make any adjustments when the car is moving, which doesn't make sense since the remote comes out for a passenger to use.
