I'm many years out of date with LRs now, but in the dim'n'distant days of yesteryonk, only those that left the factory as 'County Station Wagon' models could be classed as cars, while those with a total (IIRC...) of 9 seats would be classed as minibuses, while all the rest were vans. This classification could - perhaps - still haunt the many ground-up rebuilds out there if they're still on their original VIN?
