It was a show called "Rides" that I hadn't seen before, or heard anything about. But it was AWESOME! Focused mainly on custom-built street rods, very high-end. Featured custom car maker Chip Foose and his project to re-work a new Ford Thunderbird for the SEMA show in Vegas. Here's a link to some pics of that car:

But it also gave some great shots of other classic rods, including the custom that was the prototype for the Prowler.
TLC isn't showing it on their upcoming schedule again, but keep your eyes peeled for it, and definitely check it out!!!
