It's red, and the body is really not too bad for the age of the car - some rust patches. It shows 55,000-plus miles, and the steering wheel, gauges, dashboard, windshield, visors, rearview mirror, side mirrors, seats (think there is only one small rip along the seam in one of the seats) all look ok. It has a black convertible top, but I don't know what condition that is in.
It looks as though it has "most" of the necessary engine parts -

My guess is it would have to be advertised only as a restoration project, but don't have a clue about the asking price. My son's description was an encouraging "everything needs to be replaced."
I checked one classic-car site and a 73 850 Spider was described as being "very rare" and pretty much nonexistent now in all of Italy! (I was impressed, but don't know whether any prospective buyers would be.) I found one site nearby (we're in No. Virginia) called DCFiats.org in D.C. and asked this question there, but nobody has gotten back to me. I found your site on their site and when I saw so many recent (and enthusiastic) postings on this site, I thought I'd give it a try.
Any information anyone would be willing to give me would be much appreciated.
Thanks in advance.
