I may be reaching a little, but I’d like to give “Project Binky” a push, which you can find on Youtube.
Two dudes who run a race shop affably set about building up a knackered old Mini, up to and including stuffing in a much larger 2+liter Japanese engine into it–which is not dissimilar to trying to stuff an elephant into a dog’s house. Predictably, this quickly spirals out of control as so much fabrication needs to be done. It’s been years. They’re still at it. It may be a trifle stodgy if you’re utterly disinterested in cars, but they’re goofily charming in their own way and that sells it.
They’re pretty affable, they’ve been lifelong friends and business partners, so there’s none of that forced drama nonsense. They have moderately dorky senses of humour. They are very capable fabricators and mechanics. We find it a compelling watch (and I say this as having watched a fair bit of that baking show that had Sandy Toksvig in it as well).
If you like car shows, the old Roadkill series was a great watch. Two American dudes who also get along (so again, there’s no manufactured drama) get themselves a terribly clapped-out old car each episode and limp it back home, or through various idiotic adventures. Eventually they start getting massive sponsorship deals and the show segues from a struggle against automotive adversity to a 30 minute commercial for 700+ horsepower engines, so when you start seeing Hellcat logos, it’s time to check out.
