This set may not be UK legal - the speedo is in Km/PH only. However, an MOT examiner would have to spot that and if you've got and use historic exemption from MOT then nobody is going to complain. Caveat - your insurance company might query why you dispensed with an annual MOT and/or use it's absence as evidence of a lack of proper maintenance should the worst happen..
Guy,
The speedo is not tested during an MOT, but is required by Construction and Use regulations if
the vehicle is registered after April 84. Its system of measurement i.e. mph/kph is immaterial.
The current odo reading is recorded whether in mph or kph.
On insurance, as an MOT is not required after 40 years of age, a claim will be judged on evidence
of fitness for the road only. Proper maintenance on such a car does not include having a current MOT.
