Just going to chime in here.
Be patient if you rush in to buy something you really didn't want, then you end up waiting a few more years because you wont be able to justify selling and buying again so soon. The only thing I can say different about that is the color. When it comes the a rare car, you really shouldn't be too picky about the color. It is a pleasure just to be able to own an Eagle. The ones you are looking at look like they could use fresh paint anyway.
When I bought my SX/4 I had been driving by it for several months. It was parked in the ditch on the side of the road with a for sale sign in the window. I fell in love with the car but kept telling myself I couldn't afford it. I didn't even know how much the guy wanted for the car but if it was sitting for sale that long it had to be over priced. After about 6 months, I finally stopped a wrote down the phone number on the sign and went home. I called the number and asked the guy how much he was asking for the car. He was shocked that I called, he said the car was $1,500 negotiable. And he said I was the 1st person to call him about the car. He explained that he had bought the car from the 1st owner and the engine was making a weird noise and he is not a mechanic so he just wanted to get rid of the car. It had 69,000 original miles on it, original AMC floor mats, sun roof, CB/radio, original spare tire, jack and spare tire cover, rear wiper and defroster, factory A/C, 5 speed T5, Factory Fog lights, Everything works all in amazing shape. We met at the car and I had $1200 cash in my pocket. I looked the car over and fired up the engine and sure enough a loud noise came from the engine. I turned and offered him the $1200, and he accepted. I drove the car home and put in a new water pump. The noise was the water pump bushing going out, causing a howling sound.
One thing you have to remember. "Money Talks" Don't ever hash out a deal with somebody and then not have the money to follow up the deal. A seller hates that. If you are asking less that the seller is asking, try having the money in your pocket all in smaller bills like $20's. Many times people are selling because they have to. Spread that money out on the table, when they see it is real, it is easier for them to mentally see that ($1200 of something is way more than $1500 of nothing.)
