I have mixed feelings about the whole thing, probably like most, they change the more I start to understand the whole debate. My problem is, whilst I had heard of some issues that I didn't fully understand 18 months ago, I spent a lot of cash on a fairly sizeable diesel powered car. I was invited back to the dealership a month or two ago, and was surprised to see that almost every vehicle he had for sale was the same diesel powered variant. If you look at the 40K plus market at the moment, it's top heavy with diesel engines and they are still selling them in high numbers. I can't ignore one particular section on my commute when I drop down off a railway bridge in a built up area, especially on a nice day when you can actually taste the change in the air but I'm not sure if it's particularly diesel over petrol that's in the air. Long and short, from what I see, it's going to take years before we see the back of diesel.
