Based on the above numbers...I'd say no way. That's not a good enough deal to risk a potential problem.
Check out the "Cars for Sale" forum. Many nice cars there for similar money. At least in our forum, you can speak to the actual owner of the car and make a better decision.
Based on the above...I vote NO!
