Welcome


The Zumhagen Company LLC Specialty & Sports Car Sale Advisor - CZ Auto Advisor

​

Based in Ann Arbor, Michigan, we are an independent automotive service whose mission is to help owners of sports & specialty cars sell their prized vehicles - while reducing or eliminating the stress, uncertainty and unfamiliarity of the selling process. We are fellow Car Guys who share your enthusiasm for sports/specialty cars and enjoy acting as car consultants and the car concierge for our clients. For us, as well as most of you, it’s personal – and so are our services.

​

In these busy times, people who want to sell their Porsche, Mercedes, Audi, Ferrari, BMW or other fine automobiles simply:

​

  • Don’t have the time

  • Don’t have all the knowledge

  • Don’t want to field the calls

  • Don’t want to show the car to strangers at their home or workplace

  • Don't feel comfortable with negotiations

  • Don’t want any or all of the hassle
     

If this sounds like you, just call or email.

​

We have helped owners of over 100 cars to sell them well. With considerable knowledge of Audis, BMWs, Ferraris, Mercedes-Benzs, Porsches, and other fine automobiles, we can advise and help selling owners. We own, or have owned and/or sold sports and specialty cars of many makes and generations – from early air-cooled Porsche 356s and 911s to earlier and late model Jaguar, Ferrari,  Audi, BMW, Mercedes and other fine and special vehicles of all kinds.

​

How Does It All Work?

​

We offer services (see the SERVICES tab here) that will help you prepare to, and sell your car - via ads on national sites (AutoTrader, Cars.com, et al, plus a confidential mailing list, all via SellYourSporstCar.net, LLC), through internet and related forums including the Porsche Club of America, BMW Owners Club, Audi Club and related publications, as well as our network of interested buyers and personal contacts. We charge flat fees for our menu of pre-sale services, with an agreed success fee when your vehicle sells and you are fully paid.

 

What's My Car Worth?

​

That depends on many factors, such as the specific vehicle itself and its market supply & demand; condition, mileage, features & options, geography, etc. Understanding all of that and more, one of our services offered is a thorough valuation/appraisal of your vehicle, based on comparable car actual selling prices, asking prices, as well as our experience and expertise.
