So, I do all the office support for a shop that does aftermarket leather interior, sunroofs, and electronics. Well, sometimes people make mistakes. We had two identical Civics in the shop โ€” one to get just seat heaters and the other to get a sunroof. There's now an 18"x24" hole in the roof of the seat heater car.

So what's the biggest mistake that you've seen in your shops, oppo?
