Exactly, sales reps dont know shit.
When I went new car shopping with the gfriend for her mazda 3 and we were looking at the engine, he tells me that the only things to touch in the engine bay were the thing marked in yellow. They were the dip stick, engine oil cover and radiator cap. I pointed to the powersteering and ac compressor and asked himwhat they were and he said that he didnt know and that we should not touch anything else that the yellow things.
