One thing that is mandatory ,yet I doubt ever gets tested .....
"speedometer is working correctly and gives an accurate reading"
obviously speedos are NEVER tested on AUDIs, Golf GTIs (or golfs pretending to be GTI, with Ebay badges,) etc
A few years back ... maybe 10/13 ..... I presented an Astra G for test with a none working speedo/odometer.
The car passed without comment! (eventually )
