Smith and Sniff. It's Johnny Smith (of 5th Gear, Late Brake Show YT channel fame) and Richard Porter (of off Top Gear producer and otherwise general very well known and respected in the behind the scenes car journo world fame).
Absolutely hilarious conversation. It's not about the Top Trump type of 'petrrolhead' that seems to be so popular these days. It's a couple of middle aged guys who have a pure passion for anything automotive and have been in the industry for a very long time.
