OK guys, what sort of car would make you give up a testicle ? Maserati, Porsche, Ferrari? Hmm, some guy is giving up a ball to purchase his dream car …. a Nissan. Evidently the going rate in the US for a testicle is $35,000, the exact price for a Nissan 370Z V6 Coupe.The guy is happy to donate to medical science in return to be sitting (even if a tad lobsided) behind the wheel of a coupe.
