Initially, I was going to post this to the "Mass change model info thread", but then Exiv came first, but I thought this request should enough to give its own dedicated thread.

For a very long time, I've been nabbing a bunch of the Alphard and Vellfire entries to correct their generic chassis codes in the past, I'm talking about to those having their drivetrain being unknown or unidentified. As all currently listed, they were wrongly listed with the four or five end digits taken from their official codes that Toyota has given. Wikipedia has already correspond the official generic generation codes for a long time now.

First generation:
[NH10W] and [H10W] weren't the correct ones, please change all of them to [AH10].

Second generation:
[H20W] wasn't the correct one, please change all of them to [AH20].

Third generation:
This was already requested but to be more detailed, [GH30W] and [H30W] weren't the correct ones, please change them to [AH30].

If I become a moderator of IMCDb, I would've changed them all by myself.
