Thanks - actually a little too big for our needs, and getting on for £80K! Diesel Berlingo - less than £25000, and well over 350 miles on one tank of fuel. Guess which I will probably be buying.I don't keep a record of all releases but the Merc on the link below is a new release of something easily capable of carrying what you want to. You'd have to do a charge during the run to cover 350 miles but that need only take under 30 minute at its 110 kW charge rate.
Not cheap though, e-cars never will be.
You'd have to wait slightly longer for as big choice of Berlingo type vehicles, so far the makers have concentrated on hatches of all sizes, very fast stuff, crossovers and now a wide range of vans. Seeing all the vans I imagine more vehicles like the Berlingo will be next. Of course Covid-19 with dealerships closed and shows cancelled has slowed this years big program of launches.
