An ultra-rare 1998 Mercedes-Benz CLK GTR is heading to auction next month and is expected to sell for between $8.5 million and $10 million.

Mercedes-Benz raced the CLK GTR in the FIA GT Championship and had to build a road-going variant to meet homologation requirements. In total, apart from two prototypes, 26 road-going CLK GTR models were built for customers, 20 Coupes and six Roadsters.

This 1998 example being auctioned off by Gooding & Company is the ninth of the 26 cars built and was sold new in 1997 to Hermann-Dieter Eschmann in Germany. Eschmann owned the car until around 2005 when it was sold to a private collector in Hong Kong. In 2017, the car was purchased by Cheval Trust in Seattle and imported under the Show or Display exemption. The current consignor bought the car in 2017 and it currently has just 1,442 km (896 miles) on the clock.

The iconic race-car-for-the-road is being sold with a battery charger, torque wrench, socket set, and wooden blocks that it can rest on while the onboard hydraulic jacks are being used. It is also being offered with complete service records.

Powering the CLK GTR is a Mercedes-AMG 6.9-liter naturally aspirated V12 that later served as the base for the 7.3-liter engine used in the CLK GTR Super Sport and various Pagani Zonda models. It pumps out 604 hp at 6,800 rpm and 572 lb-ft (775 Nm) of torque at 5,250 rpm, allowing the car to hit 62 mph (100 km/h) in just 3.8 seconds and a 214 mph (344 km/h) top speed.
