I've been looking for the OBD on eBay for my car and I can't find it. I read on another post that it was bought for $30 on eBay. So I was wondering if anyone can provide me with a link to the listing so I can buy the reader.

I don't think they cost much, just make sure which one you need, OBD1 or OBD2. I think a guy at AutoZone told me the OBD2s are about $30 from them too.
I just looked at eBay Motors. Go to Parts and Accessories -> Automotive Tools and search for "obd2". I see a couple that are "Buy it Now" for less than $40.00 but you can always bid lower.

the cheap ones come with a manual containing codes for most vehicles..the more $ ones tell you the problem directly on the screen. Personally I'd spend the money to get a better one. Or, just go to Autozone and they can scan it for you for FREE
There are four distinct protocols in use today for OBD-II. Most readers offer all but the latest, known as CAN. Your car does not use CAN for this port and I don't recall which protocol it does use.
In just a few years, all cars will have CAN at that port, so you might want to spend a bit more for one that does this protocol as well. Most so-called universal readers do not understand CAN.
Also, unless you get something quite a bit more expensive than a generic reader, you will only get engine codes.

Yes, they are universal. The only thing you have to know is that the OBD-I is for earlier model cars, and the OBD-II for later ones. Sorry, but I don't remember the exact year, but I do think the change was before 1999.

With four competing protocols, they are anything but universal. Some are sold with the claim that they are, which usually means that they work for all but CAN. I don't recall the names for the protocols (since I seldom care what they are called) but M-B uses the same as other European makes.
If you limit your search to models which support all three legacy protocols (or all four, including CAN), you still need to decide on features. The cheaper models (like my $100 Actron) don't show freeze-frame data, which is recorded when a fault is first logged. Mine does show emissions readiness, but some do not.
None of these will show anything from the other computers in your car. You need a dedicated scanner for that.
