your replacements, provided the shell of the car is on the higher end of still looking nice, might keep you toward the high end of the book value. But the mileage on the car is your killer on the value. None of your replacements really impact the long term wear on the powerpack and drivetrain.

To hit the price you were thinking, my best guess is you either need a rather unsavy buyer or someone with more money than sense who needs a car right then that very day. The latter are hard to come by.
