I have the 1.9 straight diesel van, it's a nice little van. I'd say the reliability depends on a bit of luck, how the last owner drove it and like the guys here say keeping ontop of the servicing.
I have to say it isn't the fastest thing in the world
I've also got the 1.9 and it's fine provided you don't want to overtake in a hurry or speed up a steep hill. With a heavy load in it will labour. Having said that we've just been down to Cornwall and back with 4 people in the car and a boot full of camping stuff and whilst it was slow I was overtaking a fair number of other vehicles, just not very quickly.
Security system should not fail safe!
