At Moon Auto Parts, used engines and transmissions are selected based on condition, not just age. Many still have strong performance potential and offer a reliable solution for vehicle repairs. These parts help drivers avoid the high cost of new components while restoring drivability. We visually inspect units for wear and damage before sale. Customers appreciate the balance between affordability and dependable operation. Choosing used also supports recycling and reduces waste. Secondhand can still mean high value when the part is chosen carefully and installed correctly.
