So what's the price for this German-American hybrid? Currently around $55,000. Although, the car is currently located in Saarbrucken, Germany. We aren't sure how it would work to import a car like this, but chances are it wouldn't be easy. From the outside, this Z4 almost looks stock thanks to black OEM wheels, but on the inside it's clear that this machine means business. The whole interior is filled with a neon green roll cage, which is an excellent contrast to the all-black exterior. Most of the BMW interior trim seems to be stripped out, so we wouldn't recommend using it as a daily driver. Under the hood, the Viper V10 looks massive sitting in the tiny German coupe.
