cars with rebuilt engine good?

I was wondering if cars with rebuilt engine are ok to buy?

I'm thinking a 94 Volvo that has a rebuilt engine.

Is it generally a bad idea to buy a car with a rebuilt engine?
Why?

Thanks,

David

It kind of depends on the quallity of the rebuild. Find out where had the motor rebuilt or where he purchased the rebuilt. I'd definatly have the car inspected by a shop before you buy the car. Especially if the rebuild was recent.
