I have to agree with you there. I have driven several Pacificas and I can say that the engine is quite stout. I guess the reason that we have the 3.2L is just that it came with the rest of the drivetrain. DC already had the engine and chassis sorted out in the SLK 320 so that is what they went with. Personally, I find the engine suits my needs just fine, but like someone else said, another 50 HP wouldn't hurt. . .
