Does adding an aftermarket sunroof deflector count as a mod? My last couple of Hondas generated way too much wind in the cabin with the sunroof open. My current Accord looks hideous with the deflector, as I installed the genuine Honda one which is unusually tall. The sunroof is unusable for me without it. I usually put all season floor + trunk mats as well. The trunk mat saved me when somehow a 1/2 gallon milk container burst in my trunk. The trunk mat contained the entire spill, and it was just a remove, rinse, dry, reinstall event instead of what might have been.
oh wait! How about a spare tire and jack kit?
