My car has 80,000 miles and frankly after 5 years it's not looking too bad inside. The main areas of wear are on the driver headrest, the door handle area and the centre console arm rest since these are the primarily touch points while I drive. Is there anything I can do to protect them from further wear? The headrest in particular looks like it's getting close to really tearing apart and of course that kind of dumb integrated (rather than removable) design makes it an expensive fix. I don't want to use a cheesy seat cover and that wouldn't help the arm rest areas anyway. I wondered if there was some kind of vinyl protection spray that would keep things from falling apart over the next 100,000 miles.
