I would verify the accuracy of the log books by checking for entries related
to the 1971 and 1975 substantial damage accident reports as mentioned by
another poster.
I would be very wary of the logs if they are not recorded.

I'm looking at at 172 that has 1100 hours since overhaul, holding 73/90
++ on all cylinders...the only thing holding me back, last overhaul was
1976...

Don't pass yet!
Are you sure that's not supposed to read 73 / 80 compressions on all
cylinders?
How many hours has it flown in the last year?
In the last 6 months?
Does it have chrome cylinders?
Does the static run-up meet the type certificate minimum rpm?
How many major overhauls and was the last one a quality job?
Is the engine on a low to mid time airframe?
Is the price discounted enough to account for the fact you may need an
overhaul soon?

I'm gonna get flamed here, but if it has been flying quite a bit recently,
makes good static rpm, has chrome
cylinders and good logbooks, you may be on to a good buy. I'd have a
pre-buy inspection done including a borescope
of the cylinders. You should also consider asking the trusted A&P to pull
a jug and inspect the camshaft. If
everything checks out okay make an offer based on the above
considerations.
