I would ask for an exchange.
I think your idea to leave the truck parked is probably the way to go. I don't usually trust salesman. Him saying go ahead and drive it, and dont worry we will still let you exchange it is a long way from them actually exchanging it. Unless they put it in writing I would stick to your guns about a replacement truck immediately.If have had the truck since Saturday, no problem exchanging it. I am somewhat upset with this, so I called my salesman to leave a voice mail to give him a heads up. He picked up live and listened to my concerns. He said there is no problem exchanging the truck for another one if I so desire. He went on to say he would like to have opportunity to make the truck right, and then if I am still unhappy with it, he would gladly exchange it. He said his main concern was to make sure that I was happy with the truck, no reservations. If that takes getting a new truck, so be it. I mentioned I would just leave the truck in the garage until Monday, and he said go drive the truck, use the heck out of it if I want, and bring it back, and he would still exchange it. Now that is customer service! I would still like to have some more opinions from you guys - I think this forum is great, I have already learned a lot. So tell me what you think! By the way, my faith in the legendary Ford reputations is restored, I was having my doubts there for awhile. They back up their products!
