Not trying to rob the thread, but I have related question simliar to the OP.
When I looked for the car I bought (now sold and looking for Black/widebody coupe) I looked for nearly 2 years. A very large number of cars that came across my path had rebuilt engines.....many of those cars were supposedly less than 100k cars.
What would would you guys rank as the top few reasons that induces the need for a rebuild ?

Well said. Yes, "rebuilds" happen because of broken head studs or bad valve guides. But, and that's a BIG but, all "rebuilds" are not "rebuilds." A "rebuild" is a comprehensive repair from the crankshaft up, including any/all case repairs needed, crank turned/polished, rods reconditioned, all lower end bearings replaced, new timing chains/guides, new piston/cyl set (or new rings as necessary), complete cylinder head refurbishment, including new valves, new guides, new springs, and machine work as necessary, new/reground cams, new/reground rocker arms, tensioners as necessary, etc.
Valve jobs are not a "rebuild." Head stud replacement is not a "rebuild." Replacing some valves due to a money shift is not a "rebuild." But, in an ad, it's real easy to write "rebuilt engine". But, I'll bet, that "rebuilt" engine isn't "rebuilt" at all 90+% of the time, it's simply been repaired. To be sure check invoices. No invoice? Move on to the next promising ad.

Also, a file should contain receipts for machine work performed on the crankcase, heads, con-rods, etc. Those receipts should be dated to line up with the time frame in which the "rebuild" was done.

I can say for certain that Porsche was not using Dilavar studs in February of 1977 when my 911S was produced. Within weeks of picking it up at Zuffenhausen my dealer in nearby Heilbronn was having to deal with loose bottom and top studs--the thing sounded like a VW. It was an embarrassment. Dilavar studs are certainly the solution to a lot of problems with the earlier 911s--and frankly, I would be surprised to see any out there still.

In my case, the rebuild of a great motor at 130K was caused by the "money shift" at the track. I spent about $10K in parts and machine shop to do that rebuild at home.

The $10K was the straight rebuild using original p's and c's.

Update on 83 911SC
Well I finally got to look at the car I described in the OP. It was indeed an 83 SC Cabriolet. It did have low milage as advertised. Unfortunatly, it was a HARD life for this car. Good points: low milage, salvagable interior, solid chassis, Cararra tensioners, clean oil free motor. Bad points: flat tires, shi*&^ paint job, butchered radio install, no service history at all.
This would make a great project car for a restoration if bought at the right price but may be more than I'm ready to take on.
