I don't feel like I can recommend many of the car oriented channels that are available because of their language or extra-automotive content that takes away from the family friendly orientation of this site.
However there are some that I highly enjoy! It is a ton of fun to me to be able to watch live footage of someone's awesome car as well as to hear the owner describe their pride and joy!
One of my very favorites is JAY LENO'S GARAGE! I have to tell you that I was pleasantly surprised to find that it seems to be the genuine passion of a true car guy without all the excess baggage that tends to creep into a show like that. So check it out at the link below!

Another one of my favorites is Chip Foose's OVERHAULIN' Show!
I love the message behind the whole show. Do something really nice for someone who deserves it and has no suspicion!
Their home base seems to be a channel called VELOCITY. Not sure on the connection but it works!
Try this link and take it from there! http://www.velocity.com/tv-shows/overhaulin/
Then carry on from there from great episode to great episode! Enjoy watching as they create some absolutely awesome cars! Watch some great people receive a great gift!
Another favorite series is SCOTTY D TV!
This guy travels around the country and does video shoots/owner interviews. Each one featuring a different guy and his car! Tons of fun to watch! Lots of great ideas!
Check out some great cars and hear their stories at:

I recommend that you turn the music down and avoid his Intro Video to keep it totally family friendly!
Here's another one that does does video features of individual car including a road test of each one. It's a lot of fun. Check out DRIVE/BIG MUSCLE at YouTube.com at:
