It may be difficult to find a car that will do 50mpg if your mileage is mostly done in town (which I'm guessing it is)?
You will potentially end up with an extra cost in the £k's per year to save maybe half your target in year 1 followed by a similar level of investment being needed in year 2 onwards.
It's a difficult one really as you will see the useful (low repair cost) life of almost any car in a couple of years. Gut feel is there's at least a year left in the Mondeo before it's time to think about changing
