I haven't heard of a new season in the works yet, but they do occasionally rerun seasons 1 and 2 at different times. Occasionally there'll be a week where they play like 5 episodes in a day and sometimes there's weeks with none at all.
DVR-ing is definitely the way to go though, between all the filler and commercials I can run through a 30 minute show in about 11. I swear, the whole show is [theme song -> commercial -> "previously on cafe racer..." -> actual new content -> "next week on cafe racer..."] rinse, wash, repeat (usually two of these cycles per show). If you can't find it on TV, try searching links on sidereel.com if you're savvy with that kind of thing.
Still, I like seeing expensive cafe builds so until something with more meat on its bones comes along, I'm hooked.
