Pre-ordered my Trek Armor shade and Trek Armor grab handles. The rear ones have already paid for themselves since my non neutered dog leaves stuff behind sometimes. After my dog threw up all over the rear seat covers I decided to pull the trigger in the front ones just in case.
I was going to LineX the inside but decided to pull the carpet and buy some AEV floor liners and they have been great. I may not do LineX at this point. Only other interior mod I think I might do is Hot Heads. However I rarely park in the sun for any length of time, but the sound deadening might be worth it.
