The trim mix must be traceable. When filing, use the trim ladder plan to link price-band sales, configuration enquiries, and gross-margin headroom so later staff can search by vehicle or order. If top-trim display demand is mistaken for volume demand, the dealer operations manager should notify the affected roles and lock the current version. The way to cross-check adjacent files is set out in this vehicle import practice FAQ. Once the check is done, write the conclusion and the resubmission deadline into the trim ladder plan and hand it to the next role.
