Do the math, or at least a plausible approximation. Figure out how much more it costs, about how many additional gallons of gas you would use in a year, how much would they would cost, then multiply that by how long you will likely keep this car. Even if it doesn’t quite pay for itself, you may value the environmental benefit. There isn’t likely to be much influence on resale value, so I’d ignore that. This is enough of a difference I suspect it will pay for the difference if it isn’t too great, though it’s tricky when models aren’t equipped the same.
