I have to recommend 'For the love of cars', if you haven't seen it yet. It's quite new to me, and I watched all 7 episodes in a couple of days. I haven't seen a post about it yet, and it's still a pretty recent show, so I thought I'd share it.

The main presenter is a cockney chap, not a huuuge petrolhead, but he is still likeable. Ant, the mechanic, has a true passion for cars. They choose 6 iconic british cars and fix 'em up for auction, and you get a bit of history behind all of them.

Check it out, it's around 40 minutes an episode.
Here are all 7, posted in order...
(Escort Mexico, Land Rover series 1, Triumph Stag, Mini Cooper, MG TC, Delorean, Auction)
