That's a shame.
I like Ed China, he is quite charismatic and comes across as very genuine, even if some of his repairs in earlier shows were a bit of a bodge. I wish him luck and look forward to seeing what he gets involved with.
As for Mike Brewer. Nothing against him, but he's a typical 'Jack the Lad' car dealer type. He doesn't know that much about cars either judging from some of the rubbish he's come out with.
I'll be surprised if the next series of Wheeler Dealers without Ed is as successful as previous ones. Look what happened to Top Gear!
It is impossible for anything digital to sound analogue, because it isn't analogue!
