If a car has a rebuilt engine is it consider new
No, still a used car, and worth the same as the guide will value it. It might sell fast with the buyer knowing the engine is rebuilt.
Just keep all paperwork/receipts for the rebuilt engine, it might help you negotiate a better price with any potential buyers.
