It can find weird issues. I did a carfax on a car that had a mileage error. Something like it was serviced in 2005 with 30,000 miles and servied in 2006 with 20,000 miles. Things like that you want to know.
Like said above I would also have Acura look the car over, do compression checks, etc and fax you the results. If you pay to have it done, the seller shouldn't mind.
