As I have posted here a few times, I have been looking for a 32 for a few months. In reading thru the posts here this morning, seems a lot more activity on the 55's than the 32's. Assume it is related to production numbers. Since the performance specs look pretty close, what are the advantages of a 55? According to fueleconomy.gov, the gas mileage seems markedly worse. Other than torque, why a 55?
