In general, I prefer newer car, higher miles. Most likely, many of those miles are highway miles, so little wear and tear on the drivetrain. The main wear & tear is from start/stop cycles (starting from a dead stop like in city driving). Look to see when the brake pads were changed. That might indicate how the PO drove the vehicle. If mostly highway miles, the pads should have plenty of material. The elements is also another major factor that wears the car. Age, UV light, extreme heat/cold, moisture, etc. degrade the rubber, rust bolts, harden seals, etc.
