Conor McGregor is all about spreading the wealth -- buying his entire family brand new BMW 5 Series whips after he got rich in the UFC ... this according to Conor's dad.
Tony McGregor spoke with The Independent in Ireland ... and explained how the UFC surprised his family with a gaggle of Beamers back in 2015.
"He came home from an American trip last year, and I saw this fleet of cars coming around the corner with him in the lead car, a black BMW 5 Series," Tony said.
