[jQuery] Architect This: Cascading dropdowns :)


I have 2 dropdown lists (car and color). when I choose my car, I want
my distinct list of colors. After i select both, I want to display
how many are in stock.
I thought about pushing down to the client a string array/JSON object
something like this when the page loads ({Civic:Blue:3},{Civic:Red:2},
etc...)
Ideas on implementation?
Thanks everyone!
