Toyotas are the best. I used to drive cab back in the day and we had many scion xbs and Priuses with over 500k. Camrys with over 350k...

And crown Vic's with over a million miles.

You can buy wax floor repair kits on Amazon. My favorite are the ones that come with multiple colors and a heating iron. It looks similar to a soldering iron. Just melt a bit of wax with the tool and put it in the hole, then smooth it with a plastic tool that comes in the kit. Quick and easy
