My parents own a Dutch 'Stripped' Disco3 Commercial with an autobox. It has air suspension, aircon, radio/cd player, cruise control and electric windows. No navi, there's a small shelf where the screen would be.
Not all Dutch commercial D3's are stripped down versions.
I don't know if the D4 was ever sold stripped down, but they are available as commercial cars. I did a quick search on trading websites and I didn't find any stripped down cars. Of course this doesn't mean there are none.
D3s with a manual gearbox are pretty rare in The Netherlands and I've never seen a D4 with a manual, but then again I rarely take a good look at them when I see one.
If your set on having a manual you'll probably have more luck finding one in Belgium.
In case you want to look around on Dutch websites, we call our commercial cars ' grijs kenteken ' cars or just ' commercial '. Other then the international car trading sites people often use www.marktplaats.nl to advertise their cars.
