Woa - this thread exploded. Sorry, I've just got back from lunch.
As one person guessed, its the new Fiesta. However its not the Econetic (which gets 86mpg extra urban!). Its just the 1.6TDCI.
Now I was expecting a negative reply, and the 'ignorance' comments. However I think this is a perfectly logical decision. Buying this car will be a far cheaper alternative to my current situation.
It will mean I know exactly what my outgoings regarding getting to work and back are for the next 3 or 4 years. No unexpected breakdowns, no hassle, no more getting my hands dirty.
As for the exact purpose. I do a 100 mile commute every day. So yes, an efficient diesel is the right option. As for the 'no small car can handle a motorway'. Well, this isn't a small car. Its almost exactly the same size as the original focus.
