I have to vote this one a 6/10. Some constructive criticism for the episode:
-The celebrity guest is really awkward. Having them sit through multiple bits and even partake in a bit themselves just seems really rough. I was completely uninterested in this week's guest and she detracted from the overall epsiode.
-The aston chase was a scripted movie-esque scene done right. Old top gear and TGT tried to do this quite a bit, but they took it much too seriously. There seemed to be equal parts real-driving and acting/scripted events (like the police) so it didn't feel overdone. Maybe the ending scene was a little much. Having all the police cars surround the boys and immediately call it done from there would be a slightly better end. No need to draw out the acting. More real driving, overall very well executed.
-Overall not enough Chris Harris. He is the real star of this series, as much as Joey is sort of the current front man. BBC: MORE CHRIS HARRIS. More of Chris sharing his opinions, doing more reviews and bits that he wants to do.
-Sabine is always 100/100, but the whole idea of passing faster cars in the golf is sort of rubbish. After the first pass, I was like "Come on, nobody is going to be pushing" Too scripted. Let Sabine show her skills in a more natural way. More of her driving the piss out of cars around the ring. Perhaps even make a Sabine-Ring segment a regular thing. She is golden and so is that track, utilize them both more.
-Extra Gear's behind the scenes content is excellent. The R8 capturing footage of the aston was epic, really cool stuff. More B-Roll stuff like that, it looked great. Make this an hour if you have the content, I bet you do. More Chris Harris.
Overall BBC, you have a winner. Please listen to my advice and carry on!
