I had an 05 Super Glide. Not sure of the mileage when I sold it but it was very reliable. Never had an issue. However, now that I own an 07 Street Bob, you definitely want the 6 speed transmission. The 06 got the six speed. The 07 got the 96 inch motor and the 6 speed. I love the 96 inch motor, but you at least want the 6 speed trans. That rocks.
