My dad has one and it's affectionately known as "The Family Fun Bus"!!
He bought it 18 months ago for £700 on eBay. Initially it had an electrical problem that kept draining the battery, but this turned out to be an easy fix as a dodgy connection somewhere. Other than that it's cost him nothing, just ticked over 125k miles and passed its mot first time last week!
Half the time my dad uses it as a van as all the seats are removable (you can see them stored in the garage in the photo).
The only problem is that it looks like, and is, a complete banger! But it's that bad, it's good!
