Should we have engine rebuilt ar buy one? on 1998 Pontiac Bonneville

While driving my car, the car slowed down until it stopped. The engin completely shut down and would not start. We have not been able to start it.

i suggest a re built. you get a great warranty. 3 yr 50k on the motor. most guys who do rebuilds only warranty 1 year.
