i too missed the show most of the time when i was there.. because of sleeping!
i have not heard that show with the car-cleaning it sounds hilarious. it is 95c for me too - assuming they would even let me buy it... the audio for the current show did not work for me.
they may restrict access to national. tv networks that offer reruns online do that.
did you try listening to the show from their site? did it work?
if not, i found one NPR station that airs Car Talk
Sundays at 1pm Eastern would that help? (it is accessible via web - i tried.)
me being 6-9 hours ahead i have it easy now... 10 am eastern = 4pm here!
