I'm currently driving a 2yr old BMW 320D Efficiency Dynamics but will be getting a new car in a few weeks time. (i've already done 55,000 miles in 2yrs)
This time I've ordered a Nissan QashQai Tecna 1.6litre Diesel.
The BMW is great (it does 750miles with one tank when driving 80-85mph or 1200 kms when driving 130-140kp/h)
but as I've got a 6month old boy it has become a bit useless.. The boot space is too small so that's why I've gone for a larger car.
