If your increase in payments (and decrease in expected maintenance / repairs) by buying the new hybrid is significantly less than $87.50 a month then it may make sense. But with hybrid prices where they are, that seems unlikely. Especially if you're currently driving a paid off vehicle, or will be paid off within the next year or two.
He said 2500 miles a month so that would be $262.50 a month for doubling fuel economy. Also with as much driving as he is doing, his current one could easily be in the 100k-150k mark already and repair costs could start creeping in.
