dude ur A6 would be like fresh on bombay streets ... but if the import scene is the only reason your not buyina a bmw then i think you should re-consider
remember even import cars are adjusted for indian conditions u getme... the suspension and stuff and relying on dates for car launch either on the paper or salesperson is dicey
being a bmw fan dude i would def opt for the 530i and the price i would guess be a couple of lakhs here and there but reachin that segment such minor differences dont really count
