How many miles can the saturn aura 2009 go?

There is no "mileage limit" for a vehicle - it all depends on how it has been maintained. A domestic vehicle, such as the Saturn, tends to have a shorter lifespan than some Asian imported vehicles (Toyota / Honda, etc). But there are no guarantees and no "for sure" situation. If the Saturn Aura you are speaking of was taken care of well, it could operate for some time yet. Just realize the risk when you purchase an older, higher mileage vehicle.
