It's fun..until you realise how much it costs.
Diesel cars are not good. The EU pushed everyone to use Diesel because it has lower carbon emissions and it also last longer per liter than petrol and cheaper in the long run (at the time), but not alot of research was done into the emissions of diesel until recently. We now know Diesel is not better than petrol, it may put less carbon in the atmosphere but it puts a lot of fine particles into the air (basily like soot) which is rarely released by petrol and these fine particles causes a lot of breathing issues. It also puts a lot of other stuff thats not good as well, (its a long list so heres the wiki link) The EU screwed up badly by pushing this before it was properly tested.
