Not uncommon. Those cars will practically run forever when properly cared for. Sounds like the engine is decent, but I would try to find out the following if the transmission ever replaced/rebuilt. Even if they're "all highway miles," I would be surprised to hear that the 4L60E had never been replaced. Assuming it was, how many miles ago? How does it feel shifting now?
Sounds like a decent deal if the body and interior are in decent shape. Let me know if you have any questions.
