Stick a random sampling of certified “car nuts” into a room with instructions to create a top ten list, and you’ll likely find the 1989 Porsche RUF CTR, better known as the Yellowbird, on that list. While we usually don’t consult eBay for you, our discerning readers, one of only six aluminum Yellowbirds ever produced, and the only one imported to North America has appeared on the auction block for ($279,000). This 2,520 lb, 3.4L twin turbo propelled Holy Grail represents the pinnacle of pistonhead prowess from a time before CAFE standards and safety regulations made the world a more secure place. Thanks to its 525 hp engine, this 23 year old RUF GmbH flagship only needs to move 4.7 pounds for every unit of horsepower it develops. With a 0-60 time of 3.7 seconds and a top speed of 215 mph, worthy of more modern supercars, the Yellowbird was clearly ahead of its time.

Items like this crop up only once, maybe twice in a lifetime. Given its rarity, it could be one of the best automotive investments you ever make, but please linger over the listing as much as you want. Our banker is on speed dial.
