Well, I suspect that a large part of the audience to these podcasts are into cars, and I bet the podcasts are about cars, if that's not going too far out on a limb. But you know, there are a lot of different kind of auto buffs out there. Some may be into classic cars, some may be into working on cars, some may be just into fords, or chevys or hondas or what have you. Other makes of cars include pontiac, toyota, jaguar, infinity, saturn, kia, rolls royce, astin-martin, mini cooper, and many more. Some of these shows may discuss how to fix cars, and I imagine that many people would find this sort of help to be extremely useful.
