I replaced all of my pads and rotors and im at 42k They all looked like they still had another 40k in them but I was sick of brake dust and went to carbon ceramic.
I thought about using dye or paint for all of the plastic parts and wrapping all of the pillars and headliner in black suede. Would look really good if it turned out but I don't want to ruin my car if I mess it up.
You know that the auto lock only applies when you unlock the car, the period of time passes without any door being opened, then it will re lock. It doesn't lock the car if you forget to.
