1. Compare some features of Taurus (such as driving fun) with Corolla is unfair to Corolla. They are not within the same class. T is full size sedan and C is compact car only.
2. Compare the reliability of second hand T with brand new C is unfair to T. How could an used car's reliability go beyond a new one? Vice versa, will an used C be trouble-free even more longer than a new T? I don't think so.
3. Gas saver, driving fun, high resale value, larger size with higher safety, forever reliability... cannot be combined at such price class as new Corolla or used Taurus. Indeed, maybe never, ever...
