The Finnjet, built by Antti Rahko, a Finnish immigrant to the United States, is everything that you could want in a car. It's made from two Mercedes station wagons and many, many other parts that Rahko has added continuously over twelve years:
Today, the machine’s meticulously detailed exterior is tastefully trimmed with 86 lights, 36 mirrors and a couple of jet engine housings, through which the exhaust is routed. [...]
The interior has seating for 10, a stove, microwave, freezer, television and two air-conditioning units. In a nod to his Finnish roots, Mr. Rahko also outfitted the passenger cabin with a functional sauna. Three batteries and three alternators provide the juice necessary to keep everything humming.
No trailer queen, the Finnjet is quite drivable and relatively economical, achieving about 25 m.p.g. on the highway, Mr. Rahko said. A fuel-stingy Mercedes turbodiesel power plant drives a dual-wheel rear axle mounted in the center of the chassis. A total of eight wheels helps ensure that tires and suspension components are not overtaxed
When asked how he could negotiate corners in such a lengthy machine, Mr. Rahko said that the Finnjet handled well, thanks to steerable rear wheels, which turn the opposite way of the front wheels. The rear axle is from a Chevy pickup truck and is installed backwards.
