Just a couple of cheap, easy mods I did on the inside of my 2013 Civic LX....The cup holder and tray padding is a thin mousepad that i cut out. It helps avoid scratches on the plastic and absorbs the condensation from the cups. The door piping just slips right in...wish I could have added it above the door handles on the rear doors but it was very tight fit and I was afraid I would scratch/break something.
