Clunking Noise From Rear

[Flybert]

I just test drove an S13 coupe and there was a clunking noise coming from the rear any time i would gas it. Is it the differential or the drive shaft? What could be the problem because everything looks good and i wanna buy it.

its probably the subframe bushings, do a search, im sure it will come up/.
