Yes different choices will suit different use cases. If I was doing low mileage with short journeys then I would consider the petrol - but there again, if that was my usage I wouldn't looking at a Transporter at all. Mine's not my main vehicle, nor do I use it for work, it's a campervan and does long journeys only. I've done 7000 miles in 6 months averaging a true 35.7mpg and never had a stationary regen or a DPF light so a diesel is the right choice for me. I couldn't handle mid 20s fuel economy, but that's just my usage. Everyone should take the decision that is right for them, whether petrol, diesel, or just get out of the market for a while if residuals concern you. Just don't get badgered by the opinions of those who shout the loudest that their choice of one or the other is the one that everyone should make, they're just trying to get validation to reassure themselves.
