I always custom order. You must let them know upfront and be very serious about it. My dealership knows I won't take it home if they let their lot personnel do their normal thing. Tell them you want it delivered in the plastic. Seats and floors will have their covers and common contact areas on the exterior will also still be covered. Then go home and do a top-notch detail and get your LSP on it.
Now I will make this comment. When mine showed up it had clear molded plastic covers on the red calipers. I had never seen this before and didn't spot it. I started to get a funny smell on the way home and pulled over to check it out. I got this off before it melted but it could have been a mess and I'd have no one but myself to blame.
