id choose the accord, u get alot for your money and the 3 series isnt as big as i would like
the saab ... well it is a saab, they're not infamous but not exactly famous for nething either
the 6 is also a good choice but mazda is owned by ford and im guessing there's been some cost cutting here and there, if it were my money id get the accord just cuz its proved itself in the past and hasnt died off
