For me it’s more a convenience issue-- moving across the country soon to FL which has insane fees and not as good of deals as in PA. I have a 3 year contract for work there so get a 3 year lease in FL, and not have to bring the car down from PA and then turn it in without worrying about moving a car again seems like a great idea. Just not finding what I want…(other option is take advantage of insane leases right now and deal with the cost to move, like a 330e).
You could do a 3 year on a 3 series, depending on the discount it’s either a little more than the 24mo or a little less. Here’s a PA example
Or get a Jetta
That’s what it looks like 
Makes the VW dealer who offered $352 a month look like a chump.
That’s allot car for the money, and sweet mpg’s too
