Based on preliminary etimate by PorscheBound this maybe a good deal.
However, I would check a few more areas before deciding.
1. Is there any coolant leak and is the Temp Gage reading normal while driving?
2. Does the AC work and blows cold air? If it is blowing cold air I would check this again the next day or when exchanging money/title.
3. While driving does the steering wheel pull to the left or right? Do this test when you're braking too.
BTW: PorscheBound that is truely a class act on your part. Thumbs up to you.
