Hi Anthony,

If it were not for your towing needs, we'd recommend you stay away from diesel as you cover such low mileage, and modern diesels don't work so well on short hops and low-speed journeys, as various components, including the DPF, can get clogged up. 

Nonetheless, diesels are usually better for towing, and you might struggle to find a good enough petrol vehicle to do that for you. An electric or hybrid model might fit the bill depending massively on your budget and if you can easily charge a car up.
