This next car comes to Erik202 who writes: Send help! (stay 6ft back) just talk me out of buying a V8 Audi S4. I might be going a little crazy from the lack of human interaction but this thing is looking so yellow and fast. And even tho the ad says it’s an auto it’s clearly a stick and it says the timing chains and guides are done and that’s only like $4600USD.

This next car comes from tipper SecondMouse who writes: OOOOH. Around my house, this car is better known as the marriage ender. It's a long, scary story, but it ended with me getting rid of an A8 that was a bad luck magnet with a terrible automatic transmission. Anyway, these S4s are much sought after, none more so than the version with the standard transmission. This example is awesome in black, RS4 wheels, and all the expensive stuff reported done to it already and still hasn't rolled the odometer. Unfortunately, it is too small to sleep in.

The C4 generation Audi S4 was the first car to wear the S4 badge and as such is commonly called the Ur-S4, Ur being short for Ursprünglich or original in German. Audi was nipping at the heels of BMW and Mercedes in the sport/luxury sedan segment, and when introduced in 1991 the S4 added a well needed dose of fun to Audi's lineup of luxury sedans. The big part of Audi's recipe for creating an ///M & AMG competitor was the addition of a turbocharged engine to the quattro equipped sedan. Turbo Audis had been around before, but the 2.2 liter inline-5 in the S4 was boosted to 230 horsepower and 258 ft-lbs of torque. Performance was great for the day with 0-60 in about 6 seconds and a top speed governed at 130 mph. Today we've got an example that isn't some low mile over-priced trailer queen -- and looks to be a great way to spend less than $5k and have a good time.

The V8 powered B6 generation Audi S4 is something of a jack-of-all-trades in the world of late model performance super-sedans. It isn't as fast or viscerale as an STi or Evo, but it is far more refined. The S4 might not offer as much straight line punch as an E55 AMG, but it offers a manual gearbox and the safety of all-wheel-drive. If you want a well rounded sport sedan, this is your car, and it comes in the most incredible shade of blue you'll ever see.

The B5 generation Audi A4 was introduced in 1994 and featured a longitudinally mounted engine mated to a front transaxle with optional quattro all-wheel-drive. It is a good cheap used car, and the hottest version released to the US market was the twin-turbo equipped S4. Thankfully, the product planners at Audi decided to let the USA buyers get the Avant/Wagon version and was in this generation that Audi started to legitimately challenge BMW in the compact luxury sports-sedan/wagon wars.

The B5 generation Audi S4 introduced V8 power to Audi's sport luxury compact offering...and that wasn't a bad thing for anyone involved. Perhaps a few turbo enthusiasts missed the turbo lag and monstrous maintenance costs of the outgoing 2.7T powertrain, but everybody else marveled in the sweet V8 soundtrack and power everywhere.

Last week's Porsche 928 RS Carrera reader ride from Matt has brought back flashbacks of my brief (but memorable) experience as helmsman of the 4-wheeled Unterseeboot-928. It was a car that brought a smile to my face with each time I turned the ignition key and heard the staccato bark of that V8, and not only because I was so thoroughly relieved that it actually started.

The evolution of the Porsche 928 was very much like the 911 it was designed to supersede. Each year the 928 got a little faster, a little better, but changes were kept evolutionary instead of revolutionary. The sleek-in-the-front and
bulbous-in-the-rear design was penned by Wolfgang Möbius and was one of
the first cars
to offer a polyurethane front bumper that could survive US 5 mph impact standards. In 1987 Porsche introduced the S4 version of the 928, which was more of the same, just faster and a little better looking. Find this 1987 Porsche 928 S4
