I love these things, which are common around their native France, but not so elsewhere. Although you can have one wherever you are if you successfully bid for this vintage Citroen HY van.
This particular model dates from 1980, although the design was around from 1947. More on the Wiki page. here. This one has fairly low mileage on its diesel engine (around 26,000 miles) and is said to be 'very clean and tidy' and 'very good mechanically'. It'll be ideal as a quirky delivery van or for converting to some other use (camper and coffee van are suggested on the listing).
Downside? A bad paint job by the last owner, which will need redoing from scratch. The van has been priced to reflect that, available to buy for a set price of £3,500. Lots more images and details on the listing.
