Jermaine Dupri and his Lamborghini in May 2007

*The folks who financed Jermaine Dupri’s recently repossessed $330,000 Lamborghini have sued the music producer, claiming he still owes them $80,000 for the car.

According to TMZ, Premier Financial Services filed new legal docs in Georgia Superior Court, claiming Dupri financed the white 2005 Lamborghini Murcielago in 2006 and agreed to make 58 monthly payments of $4,323.

According to the docs, Jermaine paid $70,000 up front for the car and successfully made the majority of payments, but for some reason, stopped making payments in 2009.

As a result, PFS repossessed the car and sold it off for $115,000, according to TMZ, and now they’re out for the difference – insisting they hemorrhaged $79,095 in the deal-gone-wrong. They’re suing Jermaine for their losses.
