I am enjoying it. It's basically now a comedy show with cars and bleeped out swearing, but I find it amusing in a feet-up-for-a-lazy-Sunday-evening kind of way. I found the previous incarnation utterly unwatchable.
I haven't watched it, but based on the fact that McGuinness and Flintoff are in it, I imagine the show is much funnier and likeable than before.
The bestest car I ever saw was an Aston Vantage. But maybe that's because I've never seen a DB5 in the flesh.
