I’m looking to buy a used car, I just want an “average lifespan” of a 1991 Infiniti G20. I know it depends on how the owner drived it, and how it was maintained. I would just like to know the average, I don’t want to buy a car with too many miles on it, but that’s all that’s in my price range, I just want to make sure it wont die shortly after I buy it.
