Have noticed the speedo on my 89 560 sec is over reading considerably compared to my other cars, using the Waze iPhone app and its GPS as a baseline.
Eg
40 on Waze = 48-49 on speedo
60 on Waze = 70-72 on speedo
Is this a common problem? I have standard 215/65/15 tyres and tyre pressures are all at recommended levels. My other cars speedos are 3-5mph overreading depending on speed.
I have standard 215/65/15 tyres fitted.
Cheers
