I've got a 2000 model Merc Vito 110CDi with the single, flip-up rear door and 2 seat cab. Mechanically it's bomb proof but the doors (particularly the front ones) are very rust prone.
It's a private van and it's getting harder and harder to insure. H&R insurance found a policy for me that insures it pretty much as a car. Everyone else said it had to be used in conjunction with a business. Even so, it costs me £540 per year to insure for me and any driver over 30. I'm 43 with well over 5 years NCD and live on the Surrey/Hants border.
Tax is £160, I think. Fuel consumption is around 32mpg. Parts are pricey for some stuff and cheap for othet bits.
One problem with old Vitos is the glow plugs – they die and are impossible to remove. Merc dealers allegedly soak the plug in penetrating oil, disconnect the fan, run the engine until it's boiling hot then drive the plug out with a 3/8 drive air gun on its softest setting. Any more torque and the plug breaks leaving the thread in the head, then it's head-off time.
