Could you advise me as to the best car to buy for use as a mini cab? I need an automatic to save on my clutch leg; however, I've been getting conflicting advise as to whether to go for a diesel or petrol or hybrid due to the fact that stop start small journeys can eat up the mpg on petrol engined but are potentially damaging to diesels (carbon discharge). Then there's hybrid (e.g. Prius) and potentially dud battery costs.
