There is definitely more to the hybrid/diesel debate than just bottom line MPG. I have bought new Mk2, 3, 4 and 5 Golf diesels, but before buy the new Mk7 I fortunately saw the Light.....The Oriental Rising Sun. (Enter T Spirit Prius from stage left) Over 2 years of mixed miles, the balance being Motorway trips, the overall mpg is just over 60mpg, but none of the Golfs ever cracked 50mpg But the main substance of the Prius, is the car's deep outbreathe, and then Zen silence during the ever increasing motorway queues and traffic jams, when all those around are clutching/declutching, franticaally starting/stopping for just 10 meters of travel. If the car came with a blood pressure guage, you may even get a Prius Precription from your GP.
