From my observations, on RHD cars speedo position depends on the model. Roadsters are to the right, 4/4's and +4's to the left. The speedo on the left is a bit of a pain when using a half tonneau. Another quirk seems to be that the LED which flashes when the car is immobilised doesn't seem to work on 4/4 Sports. Don.
The dash LED isn't connected on 4/4 sports but if you look under the scuttle on passenger side you can see the immobilizer flashing
LOL...that one caught me out! I took the car back to the factory as I thought the immobiliser was not working. You'd have thought that they could have extended the wire to the led on the dash!!
