The Honda Partner appears to be the sister, or brother, car to the Orthia. The only differences I can tell is the trunk. The difference I can spot is the trunk. The Partner appears to have one reverse signal located on the right side. It also looks like the trunk is "shaved" with the inner part of the tail lights gone (besides the large 1 reverse signal).
From what I have read, It is also offered as FWD and AWD with B18 and B20 blocks.
From what I also read, this is used as a company car often.
One I found that was lowered and tuned.
The interesting thing is that the Partner had a second generation!!!
