📚 Vehicle History

Brand Heritage:

Isuzu, known for its robust trucks and SUVs, ventured into the minivan segment through a strategic partnership with General Motors and Honda. This collaboration allowed Isuzu to offer a competitive minivan without developing one from scratch.

Model Evolution:

The Isuzu Oasis was produced from 1996 to 1998, making the 1999 model year actually part of the second generation, which was based on the second-generation Honda Odyssey (RB1 chassis, unlike the first gen's RL1). However, the product information specifically states '1999 Isuzu Oasis' which would imply a continuation of the previous generation or an update. Given the 'GM U-Body' platform, it is most likely referring to the first generation which was a rebadge of the Honda Odyssey.

Production Years:

1996-1999

Manufacturing Location:

Alliston, Ontario, Canada (as part of Honda of Canada Mfg.)
