need advice on a little issue.

[Two560Two]

I am looking into buy a very very clean 1989 300sel with very high mileage! Car is mechanically perfect and has every service history avaliable. Car has a slight issue in the carfax. Car has never been in any accidents and has consistent mileage history but has an "exceeds mechanical limits" title. Car has 287k miles. Owner never told me anything about this but the car is clean, and checks out. no rust or body damage Should i buy this car? apparenty, as carfax reports, this car has a "exceeds mechanical limitis" title which was issued at 25k miles in 1993. I dont understand how this car can get this title at that mileage. I also used autocheck and info is the same as carfax. I dont know why this was done. According to carfax, you only get this title if you only have a 5 digit odometer when the odo turns from 99,999 to 00,000 all over again.
