Guys,
My suggestion would be to leave the seller alone.
Offer him a price, that you are willing to buy for. If he likes your offer he will contact you.
Secondly, no matter how high one prices his car, it will sell for the market price only.. So eventually he has to come down.
By the way, a friend of mine recently bought a 90 civic for around 400k. It was painted from outside but the condition was great.
