I agree with just about every post in this thread and follow almost all of them. Great recommendations.
I want to highlight
Speed Academy: They are a great Canadian channel with plenty of builds ranging from the ASS2000, K Swapped 240, E46 M3 Drift car. Currently they are rebuilding an E46 M3 as a super car killer:
They are even running a competition between YouTube channels to
race their prepped miata.

Cleetus McFarland is a fav for the shop synergy. They truly love doing what they are doing.
Tavarish needs to finish a damn project or at least status update more often.
TheStraightPipes are fun to watch.
AlexOnAutos is extremely techincal and I love his approach for seating comfort/adjustability, storage, range and so on.
The Fast Lane Car has fun with reviews. Their truck testing is brutal and evens the playing field.
