genji:..1) Diesel stinks. When you fill up, the odour gets on your hands even if you wear gloves, and it stinks when it comes out the back. 2) It's an oil, so if you spill it on your clothes, it's there forever. I suppose you diesel owners wear overalls to fill up. 3) Diesel motors sound like tanks when they start up, and make the neighbours' dogs bark. 4) Just how is diesel cleaner than petrol? Haven't you been near a bus / truck / accelerating diesel car, or doesn't smoke/soot count as pollution these days? 5) Diesel spills on roads are a great way to kill motorcyclists. 6) Diesel isn't cheaper than petrol - it takes almost 50,000 miles for a diesel to become cheaper than the equivalent petrol. As a regular urban pedestrian, cyclist & motorcyclist, I beseech you not to buy one of these monstrosities!
As a diesel car driver I've gotta admit, if I could buy a petrol car with similar kind of fuel consumption, I'd go for the petrol version every time. Despite their progress, diesel engines are still nowhere near as refined and smooth as their petrol equivalents and still have a far narrower power band.
However I believe you are over blowing the case against diesels somewhat. So to answer your points:
1) Diesels do stink a bit when you're filling up, but that's about it. The odour does not get on my hands or clothes and there is no further discernable odour once I leave the petrol station. 2) You suppose incorrectly. You've gotta be pretty careless to get fuel on clothes, but if you do as long as you don't light a match, it really is no big deal. 3) Yes, diesels, although much improved these days, still rattle a bit when starting up, but I've had no complaints from neighbours or their dogs and no barking either. 4) That is a valid question; I believe the jury is still out on that, with both petool and diesel being cleaner in certain areas. 5) Can you provide verified stats to back up this claim? Is diesel is any more dangerous than petrol, engine oil and other chemical fluids in this regard? 6) The cost/value question is open to debate. However, although in the UK diesel is more expensive than petrol and diesel cars are generally dearer than their petrol equivalents, aside from lower fuel consumption, diesel cars do tend to hold their values better. Add the ever decreasing cost of road tax for diesels to the equation and the economic case for diesel begins to stack up.
But to repeat, I'm not defending diesels just for the sake of it, as I still prefer petrol cars for driving pleasure and refinement and I hope petrol engines continue to become more efficient and reverse the losing market share trend. However, currently there is much to be said in favour of diesels, at least for a significant proportion of drivers and the kind journeys they have to take day in day out.
