I managed to watch the episodes online (I don't have Quest), and I must say I do like this show a lot. Yes, the script is not always believeable and the acting is over-the-top sometimes, but I've know Bruce Crompton for years and he is a larger-than-life figure in person as well; very friendly too. His collection and the quality of his restorations are well known.
As stated before, this is a show for the general public, not a documentery for the MV crowd. This format was probably chosen so the show can be sold to TV stations worldwide (read: the US).
I hope there will be a new season made, I will certainly watch it.
