Well... the advantage is the bling bling factor (if your sub looks nice)... as for the disadvantage well there are none either otehr then it takes up more space... but you still have to make sure your sub box is the correct volume... also you have to make sure to invert the polarity on your sub so that it fires the other way... some high end HU have that built in but for other you will need to reverse wires. I hope this helps...
ps. If you really want something for the looks.. make a box with plexi back... then you will get both of both words.

One more thing is that the woofer won't last as long. A lot of coworkers of mine in the car audio department tell me the woofer wasn't designed for that direction even though it will sound the same as if were extroverted(?). But it is BLING BLING (except if you have a tiny magnet then its like tingy ting ting 
)

If you have ever hooked up a sub "inverted" you know it does not sound the same. Typically there is more distortion as tthe sounds of tinsel leads and parts of the suspension rubbing is not blocked by the cone surface. Enclosure recomendations are the same, but remember sub displacement volume is not the same. It is also more difficult to mount a grill to protect the sub. Unless you ride in the trunk, I see no advantage.

No matter what anyone says... if they are installed the proper way no one can tell a diff if teh subs are inevrted or not.
Another thing... why would you want a grill on an inverted sub ? Am I missing something here ?
And as for sound qulity... sound qulity is 80% up to the install. Good install on cheap equipment will sound better then ****ty install on high end equipment.

I have tried this with tow or threee different subs and I can hear the difference. You may not be able to, but I can. If I can, most people with ears can.
Let's see now, we have a basket, a front and rear plate, a magnet, a spider and tinsel leads on the inverted side to create disturbances with smooth flow of air from the cone. The cone not being visible should be a big indicator of why it does not sound the same. But the cone is not completely covered or protected either. Nearly anything in the trunk could swing into the terminals and short it out. Or rip a tinsel lead, two, three or four off. Not to mention objects could slide into the pole vent. I am sure that I forgot ten or twenty reasons not to do this though.

I know lots of peeps do the inverted thing for looks, but some actually have a push-pull isobaric setup. One sub is face to face with another; only one of them is powered. It theoretically makes a tighter bass because the second sub offers resistance and recenters the powered sub; similar to the difference you hear between a ported sub and a sealed one. It's a lot of money (a whole second subwoofer) for very little gain. But if you're trying to win competitions...

Yes they are both powered with a constant volume in the middle. The idea is to have equal compliance in both directions of motion.
An unpowered passive radiator (kelton type setup) is a whole different animal (radiator usually has a heavier moving mass and no motor structure).
