Here Are the Most Unusual Porsche 911 Models For Sale on Autotrader

The Porsche 911 range isn't limited to just the base-level 911 Carrera or the Carrera S coupe driven by your uncle, or your dentist, or some guy down the street. In fact, there are a lot of varieties of 911 -- and today, I'm showing you some of the strange outliers. These are five Porsche 911 models currently listed for sale on Autotrader that are a little more unusual than the typical 911s, for various reasons you'll see as you go through the list.

Cheapest: 1999 Porsche 911 Carrera 4 -- $11,788

The cheapest Porsche 911 currently listed for sale on Autotrader is this surprisingly appealing 1999 Porsche 911 Carrera 4. Finished in dark red with a gray interior, this 911 has traveled around 122,000 miles -- and I'd call it the bargain of the century, except for the fact that it features the (relatively) less desirable automatic transmission. It's offered by St. Charles Motorcars on the outer edge of the Chicago suburbs for $11,788.

Highest Mileage: 1999 Porsche 911 Carrera Cabriolet -- $16,990

The highest-mileage Porsche 911 currently listed for sale on Autotrader is this 1999 911 Carrera Cabriolet that's traveled 222,000 miles from new. Offered by Atlanta Fine Cars in the Atlanta area, this '99 911 Cabriolet is finished in silver with a gray interior -- and, unlike the cheaper model above, this one boasts a 6-speed manual transmission. It can be yours for $16,990.

Most Expensive: 2011 Porsche 911 GT3RS 4.0 -- $519,900

It may surprise you to learn that the most expensive Porsche on Autotrader isn't the brand-new GT2RS or the highly desirable 911R, but rather this one: The lesser-known 2011 911 GT3RS 4.0. The RS 4.0 was a limited-production model released at the very end of the run for the "997" version of the 911, which was sold from 2005 to 2012. RS 4.0 models scarcely come up for sale -- especially one this nice, as this one has traveled just 4,600 miles from new, and it's listed at Porsche North Scottsdale for a whopping $519,900.

Resto-Mod: 1991 Porsche 911 Coupe -- $149,900

This 1991 Porsche 911 doesn't exactly look like a 1991 Porsche 911. Indeed, it's a "resto-mod," in this case using a 1991 911 as the base car, with body panels -- and other items -- from a 1970s 911. The result is a 1970s 911 look, except with more of the modern technology, better reliability and additional power you'd get from a 1990s model. This particular resto-mod, which appears to have been carried out beautifully, is offered by Motorcar Gallery in Fort Lauderdale, Florida, for $149,900.

Unusually Modified: 1994 Porsche 911 Speedster by Strosek -- $189,888

Few cars scream "1990s" quite like Strosek-modified vehicles -- and this particular 911 is a great example. Strosek was a tuning company that modified cars with very distinctive wheels and specific headlights, usually with tiny circles like this car has. The color, too, is especially distinctive and unusual -- and this car is certainly emblematic of wealth and excess at the time when it was originally sold. This particular 911 Speedster is offered by Porsche Delaware with just 12,645 miles from new and an asking price of $189,888.
