Rick Ross Hypes Massive Car & Bike Show He's Hosting at Atlanta Estate

Rick Ross has a parade of hot wheels rolling into the Atlanta area this weekend -- hosting a massive car expo at his own crib ... and hyping it up as a come one, come all extravaganza.

The Boss gave us the scoop Wednesday on "TMZ Live" about the car and bike show going down at his Fayetteville, GA estate Saturday ... where he'll not only be showing off his own luxury/novelty vehicles -- including a tank and firetruck, among dozens of other sweet whips -- but actually scoping out tons of others that'll be on display from different owners as well.

It's essentially going to be the automobile event of the year -- at least from what Renzel is describing to us here -- and indeed ... RR says he might be looking to buy himself.

If you follow Rick on social media ... you're probably well aware of his eclectic collection, so this type of get-together makes sense for the guy. As he explains to us, this is gonna be a who's who of car aficionados -- with gear heads from all over the world -- but not just that ... there'll even be a chance for some friendly competition and prizes!

Watch how Rick breaks down the contest ... he says he's going to extreme lengths to make sure it's fair and credible -- and even shows off what's up for grabs, besides bragging rights.
