Aluminum frames?

On what year and models are the aluminum frames used?

I have seen a few aluminum framed cars that were totaled by what looked like, not out the normal front end damage. Yeah I know...what is normal front end damage? What are your experinces?

Been narowing my search for a LS based car to buy...at first I was high on the B4C Camaros, but I don't need a rear seat. And a vette is more high perforance to start with anyway. So I think that the 2002 vettes are in the my price range.

thanks

I'm no good to you at all...I'm only aware of the one on my car. Sorry. I honestly didn't know that GM offered an Aluminun frame before the C6 Z06.
