Please Help With Radio Program

[carzoom]

HI all. I'm an owner of a Lexus and I'm thinking about creating a podcast (a radio program you can play on your iPod). I would want it to have wide appeal not just to people who own Lexus' but those who don't.

Can you tell me what topics (OTHER than cars) would be really interesting to you? What types of radio programs do you listen to now. Would you want a travel program? Sports? Arts/Culture? Film?

Thanks!

Dave
