Currently have a Hyundai I30 1.6CRDI 113 bhp; getting 52mpg.
Had a BMW 120d was getting 40 doing the same journeys.
Insurance half, tax £30 instead of £165. It all adds up and to be fair aside from the power and ability to go sideways, I have as much fun on the routes I take. I quite enjoy getting the best from a car that has some deficiencies.
