Bought a car so sharp it make the feds suspicious

from Gucci Mane – What It's Gonna Be Lyrics on Rap Genius

Meaning

His new car is so expensive that federal agents are wondering how he got the money to buy it. His record sales are good, but are they good enough to buy all these brand new cars and chains?
Gucci spells it out a little clearer for us on how he gets the money to floss this hard in Truth (Not a Jeezy Diss):

I bought a Bentley Mulsanne,
it look just like Tip’s
But I never went platinum,
do you catch my drift?
