I’ve been using a BMW 320d M Sport Coupe. It looks great, plenty of room and great build quality.

Looking at CAP Monitor, this version hangs on to an excellent 44% of cost new after three-years/ 60,000-miles.

But it is not the three-year figure that is important – it is further down the line that the 3 Series Coupe has traditionally achieved its best successes.

Early Coupes are still sought after. Even younger ones at ten years old are making strong money and it is these cars that prop up the late ones – BMW has got it so right.

The 320d has got stop/start and other fuel-saving EfficientDynamics technology so I have been achieving more than 40mpg. What a great car.

Talking of saving fuel and lower C02, there has been uproar in my village. Why?

Because the 7.55am double-decker school bus has been cancelled, replaced with a 7.35am single-decker.

This means the lucky kids who manage to now get on it are at school for nearly an hour before class and the unlucky ones either have to walk four miles or, more commonly, get their parents to drive them.

Around 30 are taking their children to school – that’s 240 miles’-worth of fuel wasted per day.

So car manufacturers are doing all they can to conserve fuel, while at the same time bus companies are wasting it with a hopeless service, especially in rural areas all over the country, by making people use their cars. Integrated transport strategy? There’s no hope.

Went over to Paris to look at an early version of the new Laguna at Renault’s secret testing ground.

You may have seen the photos released a couple of weeks ago, which like some manufacturers’ are not a true reflection of what the car looks like in the metal.

The new Laguna looks like a Laguna should. Every panel is new, but its evolution, not revolution.

The French are very keen to point out, very often, how they have had to improve quality. What Renault has been producing is simply not good enough. With the new Laguna, the one to have is the estate – the styling is superb.

But as with all manufacturers the extra bit on the back comes at a premium, and sometimes the amount is too much, taking the monthly payment out of reach.

If prices for all bodystyles were closer, then there would be less five-doors and more estates, creating a better balance in the used car marketplace.
