I also have the muncie and have thought about the 5/6 speed conversion about everytime I get on the freeway but unless I was going to make it my daily driver, I don't think I ever would. It just sounds different because we're all used to driving quiet cars all day long. She cruises just fine at 75mph. Just makes a bit more noise is all. How long is it going to take make up that couple of miles to the gallon advantage enough to cover the $3500 conversion cost?
