Vauxhall Astra Sports Tourer

Electric Ultimate - I'VE RECENTLY DISCOVERED that the shape of a car's rear end plays a big role in how much dirt it attracts.

Unfortunately, being fairly low to the ground and vertical, my Vauxhall Astra Sports Tourer's back end is a veritable muck magnet.

In fact, it gets covered in road grime so quickly that I have to use the rear screen washer frequently on my daily commute. And back in the winter months, I was cleaning my Astra weekly to ensure the rear numberplate didn't become obscured. This was far less of a problem on my two previous cars: a Tesla Model 3 (which has swoopier styling) and a Volvo XC40, which, although boxy, sits higher on the road.
