The thing is, I don't know what other damage I might have done when it overheated. I'm willing to bet there'* a lot of hidden damage. Besides, where its higher mileage, who knows when something else could go wrong with it.
I'm looking into a 2001 LeSabre with 190k kms on it now. From the pictures it appears to be pretty solid, and supposedly it only needs a hand brake cable to pass inspection.
