Alfa Romeo might not thank me for saying so but secondhand Giulietta‘s look like great value to me. I would have opted for diesel every time if I was buying – until I tried out this white 1.4 TB petrol.

I’ve driven the Volkswagen Golf with a 1.4 TSI and despite being quick, it just doesn’t pack the excitement you want from a relatively small, high performance engine.

The difference is that DNA switch by the gearstick. In ‘Normal’ mode the Alfa is  Golf-like. Push the lever forward to ‘Dynamic’ and the Giulietta surges forward with an instant, unmistakable rush.

I honestly thought it was a gimmick when the car arrived. Then I realised it’s what sets the Alfa apart. Perhaps the only question is, why isn’t DNA active all the time?

The fuel gauge is almost on red now. We’ve been averaging 39mpg most of the week. Final thoughts on this great car tomorrow.
