Yeah, the $5,000 posi loses to a $500 Detroit. The most expensive diff I can think of is ARB, but even if you give benefit of the doubt that both differentials were done, it's hard to come up with generous enough prices to get that total. Wonder how hard you have to drive it for the side pipes to melt the plastic body cladding...and then burn your leg getting out. I know I can buy salad shooters for less than $10k, too. Has it really been converted from FI to carb?
