I'm choosing a Leaf to buy made 2013 and later. I've noticed that under the hood some have additional pipes, but I can not find what feature they are for.
This one from 06-2013 does have it:
This one from 05-2013 doesn't:
So what does this specific Leaf of 06-2013 can do that the 05-2013 one can't? Is it that one has a heat pump and the other doesn't? Or is it for better cooling? Is it tied to the trims or separate additional equipment?
Thanks in advance!
