The 'vans' I'm looking at come in three dirty diesels and an electric. The electric does about 100 miles if lucky. Load it up with camping stuff/bikes and you are screwed.
Also, given the NEW premium over the dino juice version, a used ONE year old EV version is the same as a five year old diesel. That's some shocking depreciation.
I'll be looking at the Pug/Toyota/VX 2.0 diesel. They seem to be reliable (loads of them about), and the only issues I've heard about is the dreaded ad-blue that seams to affect most modern diesels - probably not helped by some people's maintenance and check routines - heard it's best keep the ad-blue topped up rather than let it slowly empty.
