I don't think it will be that bad. Sure, they won't match up to Clarkson, Captain Slow & Hamster but that would be a huge ask for anyone.
I like that they have chosen some proper enthusiasts and drivers, rather than some shit TV personality like Glen Ridge or Jamie Durie.
As long as they review a good mix of mainstream and exotic cars with a sense of humour, I for one will be happy for a second (but different) dose of Top Gear every week!
