Hello!

... Welcome!

on the Woltering-Classics website!

Woltering-Classics is your competent partner for reliable and trustworthy all-round service in the field of classic automobiles and youngtimers.The main focus of our work in this area is the Mercedes-Benz brand, however, since numerous components and systems are installed across brands, classics from other manufacturers are also in good hands with us. A K-Jetronic fuel injection system works in a Porsche in a similar way to a Mercedes or other vehicle types.

We perform a wide range of repairs, such as repairs to the engine or gearbox. We also take care of the maintenance and repair of other components in the vehicle. Electrics / electronics and fuel injection systems are obviously another area of focus in our activities, thanks to our technical proximity to BOSCH. Our qualified expert team is ready to help you and provide you with advice and support.

To ensure that such a multi-faceted service is provided, a high level of know-how is required and, of course, the appropriate garage equipment as well as (now also for youngtimers) diagnostic instruments. We provide all these services for you to guarantee long-lasting satisfaction and pleasure with your classic car. Please visit this page to get an insight into our company. We look forward to assisting you.
