Posy seconded. He's weird (and I'm certain he would agree), but in a fun and interesting way. The music used in his videos is composed and recorded by himself, btw.

A recommendation of mine is Bad Obsession Motorsport. Two men in a shed put a Celica engine in an Austin Mini. So far it's taken 12 years and 41 episodes. Some astonishing engineering going there.

If you're into cars, I'll also recommend "driving 4 answers". Very well researched and presented videos about engine technology.
