Since I brought to the attention of my fellow forum members the best price on Infiniti dealership sold IPL side skirts at the time of starting this thread, in the interest of the free market, here is a link to the current lowest price of $410 (shipped) from another Infiniti dealership near my home. Too bad they don't sell K57 anymore or I would have jumped all over these deals.
