I know I'm late to the table here, but the trend seems to be that MT cars are cheaper usually only when the MT is a generic 4 or 5 speed. The precision 6 speeds (like on many sportier cars) is often about the same as an AT.
Often marketing, not actual production costs, determine pricing. If the manufacturer wants to take the price difference off the table for the consumer's decision, the best way is to make the price equal.
In the case of the V6 Accord Coupe, the price is equal, AT or MT. The thought that leaves in your mind is that the MT must be very darn good to be the same price as the AT. Clever of them, right?
