Hi, I am looking at purchasing a Metris. The air conditioning is my concern. I live in Louisiana and what to know if I really need the C09 - enhanced Air conditioning? I am looking to purchase a 2016, rather than ordering a 2017, and the existing 2016 passenger van does not have the enhanced A/C. I will be using the passenger Metris for in town driving only, but I will be hauling my dogs behind the 2nd row seats. Thanks for any input.
