He said "offered" you said "technically yes" so I'm saying "for sure, no" on the OP's initial question. As for the "designed from the outset..." argument, the VX was built on a Trooper chassis with a Rodeo dash to save $$$. Both of those vehicles had manual transmission options, so unless Isuzu was going to design a brand new auto-only firewall the VX couldn't help but be compatible with a manual transmission. It's like Tom said, the ability to swap to a manual was a side benefit of recycling existing components, not by some grand design.
