Looking for a source that has all the available standard features, options and quick-order packages available during the 2003, 2004, & 2005 model years.

I'm interested in buying a used low-mileage Ram CTD, and unfortuantely most dealers don't know anything about the products that they're selling. Sort of like option X was available with option Y but not option Z scenario, and what exactly was available with each trim level. Inclusion of package/trim prices would be an extra bonus.

Dealers online are in the habit of listing rediculously obvious standard features in their descriptions, though they're not entirely to blame with the bare-bones and generic forms they've got to fill out. I don't really care that the vehicle has a CD player... but I DO want to know which one it has and whether the four-speaker or severn-speaker Infinity sound system was chosen.

Can anyone point me in the right direction? Thanks much!
