You should see how some people keep the interiors in their 2-3 year old vehicles
You'd then understand how people let their older beater truck interiors get run down. My first toy was an 81 2wd that led a hard life and had the lowest level trim package. I twice laid house carpet in it, installed nicer buckets, made a decent center console with top pad upholstered to match the door panels I made, got a junkyard metal dash and sanded/base/cleared it, got a nice dash pad and dyed it to match, and made the mistake of zolatoning the headliner. It was butt ugly on the outside but had a comfortable and clean interior
