I hear ya. I was oohing and aahing but this is saving me £200 a year tax and about 15mpg better. Less the extra expense of diesel fuel it's probably 10mpg better realistically. I'm currently doing a run where at 1/4 tank I put £20 fuel in and see how many miles until I get to 1/4 tank. With regards to maintenance my mate owns a garage so things will get sorted at reasonable cost.
