i may check out a rust free 93 940 wagon with 250,000 miles; should i run?

there has been much discussion about this question, but not dealing with a wagon with 250,000 miles. the owner told me that it has had a timing belt replacement but pretty vague on other maintenance up to that point. when an owner tells me that " the car's been great, has needed nothing," well, as a buyer, i tend to wince a bit.

what are the red flag zones for this year and make? I have a '90 240 with 247K so i'm pretty familiar with the typical 240 woes, which in all fairness, aren't that numerous IMO.

thanks in advance,
steve
