He's right...a concrete slab gives off moisture and it goes right up into the car unless you put a plastic vapor barrier down. The carpet will hold that moisture under your car. I got two eight foot lenghts of 2x10's, laid them down flat at the width of the wheelbase, parallel to the length of the car, the stapled plastic across them, then drive the car on. This vapor barrier will allow the moisture to escape from the slab, but also return without going into your car.
