    How much is your speedo out?

    Just wondering how much everyones speedo is out ?
    when compared to a GPS ie road Angel/Sat nav etc

    Mine is about 3mph slower than the GPS gives it credit for!
    I bought a convertable in the wettest country in the world who says Scotsmen dont have a sense of humour !

    That's about the same as mine, I have my set to 95, so it beeps when I hit 100, although it doesn't actually beep, just flashes, buzzor has gone or something!

    I think you'll find that ALL speedo's are out by around 10%

    The problem with common sense, is that its not that common.

    Mine is about 3mph above the speed on the road angel.
    In my personal opinion

    Mine only over read by around 1-2 mph at 100mph, the thing is though it'll depend on tyre wear / pressure as well.

    As long as the speedo says your going fasther than you are, it's fine! Better then getting caught speeding cause you thought you were doing 30, when it was 35!

    mine is about 5mph out at 100mph. Ive found most cars to be the same. On my old lupo i went up a wheels size by 1 inch and the speedo was then perfect to the road angel.
