go clarify it with the showroom agent/manager or whoever is there. it's a showroom car for test drive. what for give the final production quality to be there.

then if u wan to buy, tell them don wan your car like this.

then when u got your actual car, go n inspect everything, after that sign off and hold your peace. open the dashboard if you have to.

as if other brand cars from japang or german don't have cheap fix like this. if it's working, then it works.
