Are extended warranties like auto shield worth it

[joecan]

I have a 2007 Chevy Aveo LS with 64,100 miles. I bought it used 4 years ago and only put about 2000 miles/yr on it. Last year I had to have a throttle body put in, this year a new battery and a left front lower ball joint and the surface rear drums and surface front rotors.

I was wondering if extended warranties like auto shield are worth it?

Would appreciate any feedback.

Thanks
