Hi Trebro,
Im not sure where n Hampshire you are, but I have a 404 I drive around Romsey and Southampton. If your local enough I could sort out a drive out in it for you.
If you have never been in a Mog and would like a go and are nearby, you are welcome to come and take a look and have a drive.
As far as driving round is concerned, I happily drive round the local lanes, even have it on the A roads, mine is happy at 45mph, but I have it over 55mph on the A roads easily enough. I use mine like a conventional pick up and and moved all kinds of things with it.
Its a different experience to other vehicles. I have more fun in the Mog at 45mph than I do in a Porsche.
Although mine isnt for sale right now, I have seen a few on ebay lately, but they all look either hopelessly expense or in need of quite a bit of work. Mine is largely standard with the addition of a LPG conversion kit from 'GOTpropane' based in the US. And I have converted it into a 4 door to make it more sociable.
