Just crossed 5,000 miles on my new 40e. So far I'm averaging a little more than 1,400 miles a month. The good news is that the majority of those miles is my commute, when I'm getting great gas mileage. The bad news is that I'm leasing at 15k miles/year. It's still pretty early in the lease, but I'm currently on track to be above the limit in a few years.
