MERBAG becomes an official partner of HK-ENGINEERING

May 2024

Crash at the Oldtimer Grand Prix 2023

The highlight of every Oldtimer Grand Prix is traditionally the night race for racing and sports cars of the fifties and early sixties.

Merbag (Mercedes-Benz Automobil AG) is an official partner of HK-ENGINEERING as of June 2024 and thus also the official Swiss sales and service centre of the world's leading Mercedes-Benz 300 SL specialist from Germany.

HK-ENGINEERING was founded in 1984 by Hans Kleissl in Polling, Bavaria, as a restoration company. Since then, the company has specialised in the restoration, trade and maintenance of the legendary Mercedes-Benz sports cars from the 1950s and 1960s. Both the coupés - also known around the world as the ‘Gullwing’ - and the roadsters are restored and maintained to the highest standards at HK-ENGINEERING. Mercedes-Benz 300 SLs from HK-ENGINEERING are among the most sought-after collector's vehicles and are sold by HK-ENGINEERING worldwide.

As Europe's leading Mercedes-Benz dealer with more than 100 years of company history, Merbag is the ideal partner for the world-famous German Mercedes-Benz 300 SL specialist. Merbag has bundled its own extensive expertise in the field of classic Mercedes-Benz vehicles in the ‘Merbag Classic Centre’ for several years. As part of the partnership with HK-ENGINEERING, the Merbag Classic Center in Schlieren will in future be the official Swiss ‘Mercedes-Benz 300 SL Competence Centre’ for the vehicles from the restoration facility in Polling and for all Mercedes-Benz 300 SLs in general. Further key locations of the Merbag Group in Europe are to be added in the medium term.

The partnership also marks the start of official classic car sales at Merbag's locations. The core is the sale of fully restored Mercedes-Benz 300 SLs from HK-ENGINEERING as well as vehicles with a special history in their original condition that bear the HK-ENGINEERING seal of approval. The vehicles are on display in the three showrooms at Merbag's Zurich locations in Schlieren, Adliswil and Zurich-Seefeld. In Adliswil, Merbag also offers professional parking spaces for classic cars and exclusive vehicles. All work on the premium classics is carried out exclusively at the Merbag Classic Centre Schlieren. HK-ENGINEERING carries out full or partial restoration projects on behalf of the customer at its specialised workshop in Polling.

‘The passion that HK-ENGINEERING brings to this unique sports car icon is unrivalled, as is the craftsmanship that has been developed to perfection to preserve this cultural asset. We are looking forward to working together and to offering our customers a piece of automotive history at the highest level at our selected locations, but also on site in Polling,’ says Thomas Kast, CEO of Merbag.

Hans Kleissl, founder of HK-ENGINEERING, is also proud. ‘For 40 years, I have seen my company, my team and myself as brand ambassadors for what are probably the most emotional vehicles that the Mercedes-Benz brand has ever produced. Co-operating with the Merbag Group as a family-run, independent and leading European sales and service partner means a lot to my life's work. We look forward to working together for the benefit of our customers.’

Merbag's distribution of the high-quality and coveted Mercedes-Benz 300 SL will be launched with an opening event in July 2024 at the Zurich-Seefeld site. The first fully restored Mercedes-Benz 300 SL Coupé available from Merbag as part of the HK-ENGINEERING collaboration will be on display. HK-ENGINEERING founder Hans Kleissl will also be on hand to present the vehicle, talk about the company's unique history and showcase other Mercedes-Benz 300 SL exhibition vehicles.
