ive got to agree with scud i wouldnt have another mercedes in any shape or form
i have a 52 plate vito (i know your looking at a newer one but its still a vito)
my problems in the last year
rear suspension coil snapped
front coil snapped
low pressure fuel pump replaced
high pressure fuel pump
had to have it re-coded
glow plug relay failed
they hate water (the slightest stonechip will turn into a rust patch)
apparently the panels are made from different quality metal to the cars
and now i recon one of my injectors is playing up
glow plug light stayed on and i was told that it would be a faulty glowplug but i was warned not to change plugs as they have a nasty habbit of snapping in the head

(i bit the bullet and they did change ok)
and most important the aftersales of my local mercedes dealer is shocking
id spend a little more and get a movano
i only got mine as it is the custom crewcab model
