Hi Darren!
I don't think the show would be the same without Cleggy. He had the best one liners. I loved the way he would speak on something that didn't relate to the conversation at all. Then honestly, he is a great actor. No one could have carried his lines like Peter did. He has great facial expressions which could make the situation even more hilarious. He just made the show what it was.
I really have three favorites.
Wesley is one of my favorites characters for what I said before. It is that belief in himself that no one else has. He just loves motors and it doesn't matter what others think. Wesley makes me laugh just as much as Billy did. Billy was a great third person I thought. He made me laugh more than the other two.
I didn't answer that well. I just can't pick one Darren.
