Thanks, I did look at YAML which has about a page in pickaxe like 
standard Marshalling, and I might use it later but for this assignment I 
just want the simplest way to reliably write and read my object 
(containing an array of objects) and read it back.  The marshalling 
*seems* to be working in that when I open the cars.data file it looks 
like it has data on the child Car objects, but I can't tell for sure yet 
until I actually figure out how to get all the way to my Car attributes 
:).

Essentially I want a statement that acts like this:

cars = CarInventory.new # handle for object which is array of Cars
if !cars.car[0].vin # grab the first car from CarInventory and check if 
the VIN is nil

That second statement does not fly and no matter how I deconstruct it I 
can't seem to get at the array that CarInventory represents here.
