where to begin?

[purple people eater]

I just bought a used 2005 touring turbo convertible and do not know much about them. I liked the way this one looked (purple with 18" rims and tires) and drove. I am already planning interior and exterior mods after reading through most of the forums but I don't know much about cars. How do I find out what came with the car (options). I have the vin. and it did not help much? I checked chryslers web site to read through what options were available new and I can not figure out what is on my car. I.E. abs brakes, premium sound, etc. where do I start? Thanks for being patient with the new guy!
