I’ve never done a full build like this, but I feel like every project I do goes over budget. As an example, yesterday I put DVD headrests into my wife 2013 Terrain. I was given the headrests and wiring from a friend so it should have been free, right? Nope. Had to buy new clips for interior panels, fuse taps, new IR headphone as the old ones weren’t working and oh yea, a new multimeter since mine went missing. Not a lot of money, but still over budget. Luckily my wife gets to reep the benefits of this project so I won’t get any complaining. Thanks again for everything you do Eric.
