I drove a Citroen Dispatch for a while – doing about 1000 miles a week. And we also had a Citroen ZX for a while. They’re fairly equivalent vehicles – same technology, same maker, same engine. Not like saying “I had a 95 Fiesta and then I got into a Vito and it was ace”.
The Dispatch (van) was slower, noisy as hell at speed, and was absolutely flat out at 80. The ride was horrendous if you had nothing in the back, and the body panels boomed like crazy over bumps. 3 people in the front was extremely cosy. And it used more juice – a lot more if you were trying to do 70 or 80 as it was effectively flat out. Handling was vague too, particularly horrible in crosswinds.
The ZX was a Audi R8 by comparison. Less slow, comfier, quieter, more room for people, used less fuel etc. Had odd sliding rear seats which made for masses of boot space if you needed it.
I’d never drive a van as my only vehicle unless I absolutely needed one for moving 8×4 sheets of ply or it was provided gratis…
