The news releases from when this was first announced say the Car Talk website will continue, and new shows (actually reruns of older shows course) will continue to be posted for downloading. Since the weekly podcasts are the way I listen anyway, the show going off the air on most PBS stations is not much of a problem for me.
One idea for the Car Talk staff to consider @cdaquila , lobby for inserting some promos into the NPR station between-shows broadcasting mentioning that Car Talk’s website remains active, with plenty of car repair knowledgeable folks offering free advice, and that new shows are available for downloading and podcast listening each and every week. I expect even the puzzler will continue on the website.
Edit: I notice we seem to be getting quite a few OP’s from Europe than we did several years ago.
