How can I find out, roughly how much a 1985 Camry was worth in 1990?

I need this info to resolve a dispute, that involved someone destroying my car (1985 Camry) in 1990.

The Kelly Blue Book, 1990 edition, will likely provide me with an answer, but I can't seem to get a hold of one.

it will take a bit of searching, but I've looked up car value's before on the internet for my car for what it was worth new. Basically just open a search engine (yahoo, Google, ect) and type in your year and model car (ex: 1985 toyota camry) and read the explanations under the links. You should eventually find a site with the info, specs, and pricing when your car was new. Hopefully that is some help to you.
