Have they said anything about episode length? 45 minutes, 1 hour?
If it's like top gear there will be certain parts of the show that are filmed very close to the air date to keep it as current as possible.
I don't have prime and don't want to pay £80 a year for it, I don't buy enough to warrant it for free deliveries, when I do I'm happy to wait a few days and have free delivery. I wouldn't use the music service and I can't see me watching anything else.
Hope Corden doesn't get anywhere near the real show, can't stand him.
Bit of a rip off of one of the challenges on getaway car or whatever that other show with the stig.
