This “full-size Hot Wheels set” comprises five 991.2 generation GT3s, alongside a rare 991.1 911 R.

The collection features a red GT3 with ceramic brakes, a GT3 RS with Weissach and Clubsport packages, a GT3 Touring, and two racing-spec models: a GT3 Cup, still in delivery film with just 20 miles, and a GT3 R, eligible for endurance racing. The 911 R, boasting carbon-ceramic brakes and Pepita bucket seats, is a highlight, with mileage under 30, Motor1 reports.

Collectively, the cars have covered less than 150 miles. The 911 R alone is estimated to be worth over half a million dollars. RM Sotheby’s will conduct an online Sealed Drop auction from April 28 to 30.

While the low mileage of the 911 R might be a selling point, the auction house suggests that the winning bidder should drive these cars. The sale will determine if buying 911s in bulk offers a discount.
