Stop in for a cup of coffee

Corvette in to check moto mounts. Yup, it has. And broken. I cant do it for a couple weeks, so putting it off until spring. Guess i should look why ram 2500 is showing 633 km/hr at a standstill. Any bets on how long this is going to take? 2 shops have looked at it already. And this is a new one to me.
Could that be the speed the earth is rotating at your latitude? :rolleyes: GPS involved somehow?
