In your case, I'd take the money. 65k miles in 6 years is a long time. It depends on your local supercharging rate but it'll take probably 5 years to break even.
In my case the situation is the opposite. I drive more than 65k in one year and I'm so much on the road that all I have available is superchargers. If I get an option to get that free, that's worth more for me.
