Yes, he's in Missouri somewhere. I've seen it posted to the St. Louis Craigslist.
The issue I see, is that at 100,000 miles, I've seen 97-00 model boxsters with similar miles selling for $6,500-7,000. Knowing this car needs a major engine overhaul just to be usable, a more fair price point is likely around $3,000 or part it out.
And personally, I'd have an issue giving $3k for a car with both known and unknown issues.
