Which if I had to guess did not get as good of fuel mileage as the Viper due to being a lot heavier and not as sleek sliding through the wind at speed. I fuel it up every other day when the weather's nice. I've had it for a little over a year now and have 15k miles on it. But as far as cost of fueling it up, pssh, almost as much as a house note each month. But if you worry about the fuel mileage of it then you shouldn't own it.
