You'd need to start looking down south, like NC and TN down south if you want something rust free.

Second, what's your budget? That will dictate what year chassis, how much mod you could expect to have, etc.

Personally, I looked for a cheap S14 chassis and found one all the way down the NC/SC border for $2500. It was stock with some minor bolt on, no rust but the had a pretty big dent in the rear quarter panel. Shocks were blown and engine had low compression but it was good enough to drive it. Didnt really matter to me since I had a full suspension setup to install and had an RB swap to put into it.
