I tend to find myself only watching a hand full of channels now, mainly discovery channel.
The shows I watch regularly
Fast 'N Loud - Gas Monkey Garage, building hot rods and auctioning them off at no-reserve, I'd say this is currently my favorite show. I think I just have an affinity with their lifestyle choices.
Wheeler Dealers - Who doesn't watch this? Watch Mike Brewer and Edd China flipping cars found in newspapers, auctions or wherever else mike can find them Edd will restore with excellent results almost always making a profit.
... Is Born Series' - A brilliant show to that has Mark Evans and friends fully restoring/building something and great tips and basics for the home mechanics, as well as information on licencing and the like, a very well rounded and much watch set of shows.
Top Gear & T.G. USA - I watch both the UK and USA versions and am impressed with both. The USA version with Rutledge Wood, Tanner Foust and Adam Ferrara, a lot of repeated UK stuff, but there is a lot more 'adventures' with american 4x4s and the like. Slightly less entertainment than UK but interesting non-the-less
Beetle Crisis - A short series initially following a couple of rebuilds, but ends following a series of vehicles based out of one shop (which has since closed down). If your a beetle fan it is a much watch, but I just watch it to remind myself of the pain involved with fixing up a vehicle, and remind myself I'm not the only one suffering. Some good tips can be found here too.
There are a tonne of other programs I watch on a much lesser sequenced arrangement, Many are good for their own merits but I tent to watch stuff for tips / inspiration / common faults etc
Other shows I watch include:
Gold Rush
Jungle Gold
Moonshiners
Mythbusters
and some stuff thats not on Discovery
Two and a Half Men
Friday Night Lights
If nothing else is on I'll watch a mixture of cartoons and or panel shows such as Family guy or Mock The Week.
What do you watch??
