My initial thoughts are to get an unconverted model initially though probably with a leisure battery. The main usage would be for weekends away (2 adults, 1 or 2 kids and a small dog) or days out (4 adults, a child or 2 and a dog). We might also have the odd longer trip once or twice a year, perhaps including a foray to the continent, depending on how comfortable we find the setup. The unconverted flavour seems to give us the most options and we can use it for a while before deciding if we want to convert it.
At the moment I don't really have a preference for petrol or diesel. I'd like something reliable that will get us where we're going, though not necessarily at break-neck speed. Is one better than the other or are they all pretty similar in terms of reliability?
From and age v mileage perspective am I better to go for fewer miles than fewer years? For example I've seen a diesel from 2000 with 100 000 miles and a 1997 V6 with 45 000 miles. Both are similar prices and the bodywork seems to be in a similar condition but would both still have a lot of life left in them? Ideally I'd like something from around 2000 with less than 60000 miles but I'm having trouble finding one of those for reasonable money. I know that European Breakdown Cover can be harder to find for older cars but the RAC and AA both seem happy to cover cars over 20 years (for a price).
Northern Bongolow has kindly offered to initiate me into all things Bongo on Sunday but I'm off for a drive around some dealers on Saturday so any advice before then would be much appreciated

Thanks a lot
