I will be changing my car in the next few weeks. I have a Toyota Corolla Petrol 1.4 at the moment. The garage I may be buying from suggested that I buy a diesel instead of another petrol as I do approx. 500 miles per week which costs around 50 euros. I don't know much about the diesel model as they haven't been out that long - does anyone have any feedback on this model, either good or bad, resale value etc.
