99 DeVille

You better run like hell.

It's more than "just headgaskets". The threads in the block fail and the headbolts pull out.

The entire engine has to come out from below to repair it and it's not a sure bet repairing the threads will be a lasting fix. That's why there are TONS of these cars in the junkyard, because fixing them exceeds the cars value.

Great cars otherwise but this is a fatal flaw.

You can get a good Camry or Accord for that price that will run nearly forever and get 10mpg better.
