The speeder is sabotaged so that the cutsceenes will triger properally when you enter the docks. The speed serves as a shourtcut so you don't have to walk so far.

The speeder also alows you to bypass the exchange's call as long as you use it to return to the landing sector.

You might also be able to get influence placing the power cell and the manuvering flaps. Enable stealth, sneak up on them, and listen to their conversation about the Juma in regards to breaking into Vogga's stash. Head to the residential modules located here and find the room with two thugs conversing. Do not talk to anyone, perform any quests, etc. You can get influence with Atton when you install the computer and influence with bao when you ask him to cheek your work when you finish repairing it. Make sure a stealth user is in your party. The air speeder is great for gaining influence. My question is: what is the point of even having it in the game? It is simply to show there are people following you around, or is there some other purpose? To be honest, it always kinda creeped me out. However, when I've played, it ends up getting mysteriously trashed, as though someone purposefully sabotaged it. You know that airspeeder you find on Nar Shaddaa in the Refugee Sector? You can fix it up and whatnot and even 'drive' it around for a lil' bit.
