Only at a relatively small number of dealerships/brands and you're getting a base model car from the service loaner fleet. It is really more intended for people who have been in accidents and their insurance is paying for the rental. The getting to pick the vehicle you want is meant to give you a like model car while yours is being glued back together. It is becoming much more common for larger dealerships to just house an Enterprise or Budget rental desk inside the dealership which manages loaning out the fleet.
