Martin from Swindon has asked us to pass on this info:-
FYI and for the other registered/non registered S-Cargo owners, something came up on my Professional institution forum today regarding vans and speed limits.
It appears that though the s-cargo has a body type of 'Van' and is 'Private Light Goods', it counts as a goods vehicle not exceeding 7.5 tonnes for speed limits purposes.
This means that on 60 mph restricted roads, the limit would be 50 and on dual carriageways, the limit would be 60.
The only exceptions to this are where a van is built on the same chassis as a car variant and has a gross weigh less than 2 Tonnes. S-Cargos are NOT based on the chassis from a saloon equivalent and therefore are outside of this exception.

See http://www.direct.gov.uk/en/TravelAndTransport/Highwaycode/DG_070304

and http://www.dft.gov.uk/pgr/roadsafety/speedmanagement/vanspeedlimits

I don't know how many people know this, and it would probably only apply if one was exceeding the written limits by sufficient margin, but it might avoid some speeding fines out there!
