Query: Worth Buying Just For The Demos!

As a self-inflicted Cars nut, I loved every minute of this album! I won't talk about what I would have included on this anthology - I think that's a good reason to buy all the other albums. All the demo suprises make it worth owning; And any die-hard Cars fan will be able to tell just from the use of instuments into what time period (i.e. Panorama era, etc.) each demo was recorded without reading the liner notes. And my favorite cut? "Cool Fool" - showcasing not only Elliot Easton's musicianship but his only songwriting collaboration with Ric Ocasek as well!
