Got a bunch of cash and want to have a "subtle" mid-life crisis? The Hennessey Jeep Grand Cherokee HPE800 starts off with their top of the line SUV and makes it a supercar. Start off with a Hemi V8 7.0L with twin turbo forced induction and you apparently get 805 hp (823 lb-ft of torque) and a 0-60 time of 3.1 seconds (1/4 mile: 10.9 @ 130 mph). Holy shite.
As you can imagine, this amount of power required an upgraded transmission and torque converter, bigger 15.1-inch Brembo brakes all around, slammed suspension, a carbon fiber front end, and alloy wheels. Yours for $235,000, and limited to only 24 units.
