Audi RS4
All hail its majesty of rip-snorting super-duper sleeper sedans, the Audi RS4. This over-the-top, under the radar rig was only sold here for two years, and you’ll be shopping the used market for one, if at all. Mostly, we love how Audi installed a throbbing 4.2L V8 with 420 horsepower and a redline of eight-freaking-thousand revs, along with a proper 6-speed stick that got gear ratios so tall you could rip it into second to pass an 18-wheeler on the highway.
