More bells and whistles begin to emerge as customers move further up the trim levels - the Platinum Fusion, for instance, includes nearly everything as standard equipment - all the latest safety technology, leather interior, dual zone climate control, a reverse sensing system, adaptive cruise control, etc. Customers who prefer to pick and choose their options may prefer to begin with the SE model and then add on their preferred packages, including the technology package and Driver's Assistance collection.
