Bozi Tatarevic is a race car mechanic, automotive writer, and all around knowledge buffet. He's sort of like an automotive detective meets crew chief. When the Ford Fiesta RS motors started blowing up, he was the one who found out why. When everyone was calling the new Supra a BMW, he found a schematic to back up that claim. He's full of interesting facts and stories, and definitely worth a follow.
