There was a time when prices for the Porsche 911 R were astronomical. Yes, it was a limited production model that sold out fast and was fitted with a purist-pleasing manual gearbox in response to consumer demand, but nothing could justify dealers charging $1 million for the privilege of owning a used example. Mercifully, prices for the 911 R are finally starting to plummet. At its recent Fort Lauderdale auction, RM Sotheby's sold a pristine example of the 911 R for a grand total of $300,000.

Granted, this is still a hefty mark-up when you consider the 911 R was originally sold for $185,000 brand new, but it's lost a lot of value in the space of just a couple of years since it was first revealed at the 2016 Geneva Motor Show. The example that went under the hammer was the 430th of the 991 that were made, finished in a unique white livery with bright blue stripes. It was also equipped with the Sport Chrono package along with other goodies. There's a simple explanation why the 911 R has dropped in value so dramatically. Porsche wasn't happy seeing the rare sports car being flipped for such ridiculously high prices, so it introduced the 911 Carrera T and the GT3 Touring Package.

Starting at just over $100,000, the Carrera T is essentially a budget version of the 911 R with a twin-turbo 3.0-liter flat-six and comes with a manual gearbox as standard. The GT3 Touring Package, on the other hand, adds, you guessed it, a six-speed manual to the GT3 at no extra cost. As a result, the 911 R simply isn't as desirable as it used to be – apart from its rarity, nothing about it is unique anymore.
