TNN Power Block
TNN has some good auto programming on weekends. The Saturday and Sunday Power Block has gotten extended to include more back-t-back shows. RaceTV, followed by NopiTV, SuperTunerTV, Car and Driver, HotRodTV, and Trucks. While I may not be into trucks, I like Stacey's delivery, and I have learned a bunch about customizing from the show.
Gotta love the host Michelle!
