I bought a running 400 in Newport news area last year. Guy was asking $15k and I paid $12k. Car sat for quite some time. It was an older resto that had passed between a couple of worthless POs.
Here is the day I brought it home. I should have paid around $10k but I was in 'love'
Not sure if that helps...sounds like you have some nice ones. There is Star City Pontiac Club close if you want some 'experts'. http://www.starcitypontiac.org/
