Hey 88, This is what you should do:
Negotiate as others have suggested. If they agree to come down on the price, but won't fix the problems, take it to an independant mechanic. He will probably charge you a little to look at it, but have him test drive the car and give you his opinion. The dealer may not want to fix everything until it is sold because the warrenty they are offering may be through a third party, which means that if you buy the car, the warrenty company will have to pay for the repairs but the dealer wont.
I bought a thunderbird a few years back. when I drove it, it had a lifter noise and it seemed to heat up a bit too fast. I talked to the dealer before I bought it and told him what I had found. He listened to it and told me he didn't hear/detect anything wrong, but he threw in a warrenty. Two weeks after I bought the car, I took it back to the dealer, said the exact same thing about the lifter and heating prob. They checked it out and it was TWO cracked heads. The warrenty covered the cost of repairs (including a top-end rebuild) and I was only out the $50 deductible. That car ran great for years with no further problems.
You may wish to do the same thing. I would definately ask them to replace the upper intake on that car before you buy, though. It is one of the only weak spots on the 95+ series II NA cars (unless it has a Supercharger). If you get the car, I'd like to check it out sometime. After all, we are practically neighbors!
Good luck in your decision!
