You are not missing something. They changed it. Maybe they want the local dealer to try to source the car for you. Makes a little sense. We bought our 2014 ML350 using the previous search engine. We went to the local MB dealer who had what we wanted (Cooled seating). But car was white and the missus wanted a black one. So I fired up the search engine and found a 2014 black one 130 miles away. Did all the negos by text and email. Went to the dealer and bought the car. Within 3 days I had 2 problems Lights over running boards didn't work. Easy exit steering wheel system didn't work. Both fixed in a day. The point is the dealership made no money on the sale, and the service dept still treated me like I was king. I'll bet you that MB changed the search engine to try to keep you from the now laborious process of searching by zip code, and instead letting your local dealer do it for you. BTW, you can streamline the search a little bit. Instead of clicking on the blue Search Inventory button, go up to the top of the page and enter your zip code. That will open a window on the left side of the screen that allows you to expand the search by distance, though you still have to go to each dealer's website. Sucks, don't it? I got a survey from MB about their website and complained that the change was not well-received. I am searching for another CPO to possibly replace my current Dodge, but it is taking too much time.
