    4.6L Talk
    I bought a used mustang gt. everything's completely fine but one thing I'm noticing is all other mustang gts have a speedometer that goes up to 150 and mine only goes up to 120. I'm thinking the stock one broke and he replaced it. Does this make sense or do some gts come with 120s?
