I am guessing you are referring to the Largo and Vanette of the same era ? The C2x series ?

The Vanette was intended for commercial use and the Largo its passenger variant. The Largo of this era shared the platform of the Vanette. Later on the Largo became a mini-Elgrand with a slightly different shared/morphed platform with the Serena (which in some markets was the Serena and then progressively became Serena globally)

So the C2x series Largo was a passenger version of the Vanette? But I have seen ones which are basic than the Vanette VX

It started off that way.....basically imagine it as a wide/large body version on the Vanette....it was intended more for passenger use..but then they also introduced variants that are somewhat suited for dual purpose use.
