If you're not stuck on getting this particular car, but are trying to find a really good deal from a motivated seller, then why not tell the seller something to the effect of, "Your asking price is not unreasonable; you can probably get what you're asking, but it may take some time to find the right buyer. I don't want to really haggle over the price; I'm just looking for a really good deal from a motivated seller -- I only have limited funds to spend on this project too -- so if you decide you want to just move the car immediately for a price substantially lower than what you're asking, please give me a call."

You may want to mention the price you want to pay (which, from your comments here, you seem to have already determined). What year 944 is it?

Whether or not you get the car will depend on the market and how well the seller knows the market, and how hungry the seller is to move the car and get the cash. If what you want to pay is way under market, you'll probably just be wasting your time doing what I suggest, but if what you want to pay is just a "really good deal" for you, the buyer, and the seller doesn't have unreasonable expectations about the value of his car, it will work.
