Could do with some help long story short. I live in Spain and bought a new Mazda 3 1.6 Diesel in 2012 the model in Spain is the Mirai (which i think is the equivalent of the TS2 in the UK) we are now moving back to UK and because i will loose too much money if i sell it here i am planning on getting it changed to UK plates which involves changing the headlights fog lights and also i need to change the speedo from KMH to MPH . To save money i wondered if these are jobs i could attempt myself or do i need a professional ?
Any advise would be appreciated

 

Lights you can change yourself but the speedo will need to be done by Mazda as it needs to be programmed into the car electronics.

 

Thanks grim_reaper i found this website that make replacement dials so if i could take the instrument cluster out i think this might be the answer , don't know how easy that would be .
