In our tow-vehicle data, 89 models have a variant published at 3,000kg braked or more, up to 8,000kg. The rating belongs to the variant rather than the nameplate, so an older or lower-spec build of the same model often tows less.
A tow rating is the ceiling on the trailer. Your car's GCM and payload decide what is left for people, fuel and gear once the van is on the back, and the compliance plates settle it.
