I think I solved it all
If you playback on a HD TV, easy peasy answer, it`s going to be full HD.
What ever the spec is, it`s the Mk3 and you just have to have it
I`m glad I only have two cars though, one with the Mk2 and a new one coming soon with Mk3, they both had to have one otherwise one would car never get driven.
Keep up the good work Sean
