Justin Bieber is a really good friend ... because just 2 days after Lil Twist crashed the singer's ultra-expensive, chromed-out Fisker Karma, Bieber's homies were behind the wheel ... again.
TMZ broke the story ... Twist crashed the Fisker into cement poles outside an L.A. liquor store Tuesday, badly damaging the front-end ... and for bad measure he fled the scene.
But Bieber hasn't connected the dots ... because Thursday, one of his pals was back on the road in the same car, which had apparently been repaired quickly.
But hey, it's just money, right?
