What kind of downloadable content would you most like to see for Borderlands post-release?

Aug, you had to add levels

Aug, you had to add levels and missions as a seperate item.  There's really no way they could do DLC without doing as added missions.  The other stuff would be boring playing through the same game because we will have already played it.

I would say, the real question is, what will they be adding with the extra levels and missions?

I'd like to see more guns... I know, it's hard to imagine how we could need more guns when there's already 650,000, but I'm in the mindset that more than likely, playing through the game, we'll think of things like "hey, I haven't found an unreal tourny shock rifle yet" or "the grenade launchers don't feel really complete" or "I wish there was some miniguns"...  Like I say, we don't know everything that's gonna be out there yet, but I'm guessing that most likely there are a few weapons catagories that just aren't in the game for lack of time/initial creativitiy/whatever.  Once I've played with every other type of gun, I'm really going to look forward to playing with more new types.

Regarding vehicals, I basically see it the same as guns, add more parts, add more capabilities, make them faster, make them stronger, maby add some race sub-missions, who knows what will/won't be in the game... but I'm sure there will be some things that we think of "oh, this vehical is fun, but I wish it had X feature"

Character skills and abilities is a no brainer if DLC includes a higher level cap.

PVP multi I have mixed feelings about.  In FPS games, the best PVP multiplayer games are skill based, they are fair between the players on the two opposing sides, and the game really comes down to who pulls off the better strategy and skill.  A game like BL is just going to be rocky, because you'll never be on equal footing with the opposing player.  Either you're going to have better equipment, or they will.  There might still be skill involved, but it would be a really massive feat making the game feel skill based in pvp multi, when the single player game is so heavily equipment focused.  I don't think the feature isn't worth having ever, I just don't think it's going to add nearly as much to the game as PVP multiplayer adds to a game like halflife or halo, where they aren't trying to balance a million weapons.
