It depends on the value of the car, the cost of the repair, and what else is wearing out. Get a written estimate and compare it with the market value of the vehicle and the cost of a replacement.
If it is steady and the car runs normally, you can usually drive short distances to a shop. If it is flashing, or the car is running rough, stop driving and get help.
Check your owner's manual or ask a shop. Belts have replacement intervals, often between 100,000 and 160,000 km, while chains are designed to last longer but are not maintenance-free.
Used is cheapest but carries the most risk. Rebuilt and remanufactured engines cost more and typically come with a better warranty. Ask about the warranty before you decide.
