Yes... new speedo in mph is about £70 plus vat or make a neat 'V' on the edge of your dial out of red tape pointing at 50kph (31mph) 100kph (62mph)
Or.... move to France or Ireland
Thanks for the offer me fellow Dorsetshire man. I actually got a new one in the garage but didn`t want to fit it just in case it was calibrated different and ended up doing 40 in a 30!
