4. When a customer wishes to play by rules other than the customary, he is on his own. So, by purchasing the part at the Wholesale Window -trade technicians and experienced DIY- the customer implies to know the universal rules that apply. It is equally valid that lack of knowledge of a law or regulation is not excuse to be found not guilty of a violation of either.
I do not know who brought up "wholesale". Anybody can buy from there. You do not have to be a technician and/or don't have be related to auto industry at all. To me "wholesaler" does not sell to consumers but they do. The prices they offer is for everyone. I did NOT get a special pricing for the part.
5. The invoice given at payment of the parts clearly states to check them before leaving because there will be no further claim accepted, except as stated on the written warranty shown there. At leaving the dealership, one becomes the owner responsible for the part and condition, as well as the conditions of sale.
Think about it. I have been at the same dealer many times buying parts so, obviously I trust them and I am happy with them until that time. Since I have my car for service there, they do not give the parts to me. SA tells me "pay for the parts and my tech will go pick it up". What was I supposed to do? I have never purchased remanufactured parts from them. Assume that they may not sell me a new part?
6. The furnishing of a coupon for labor as a courtesy by the dealer's SM is more than could be bargained, patronizing as it could have been to get rid of a complaint. The beef with the SA should have been first dealt man to man, before escalating up.
As I mentioned before, I was not even going to bring this up since the SA was an old man and I said to myself "leave him alone". Then another department's manager tells me that lately they have been having too much complaints with this specific SA. He actually almost pushes me to talk the service manager and he adds "We are here because of you (customers). If you do not mention this behavior, we do not know how we are doing". Also the discount was given to me BEFORE I found out they sold me a remanufactured part. I repeat, if I had known about the remanufactured part, I would have chosen a different route. Like I mentioned before buying a used valve body OR taking my car to another service and just change the conductor plate and take my own risk.
From the foregoing, my recommendation would be to sell the Mercedes and move up to a Trabband or a Yugo, to avoid contamination from wannabe equals. Please, I hope no offense is found because none is intended, and if the Mercedes is kept, I suggest that future service and work be searched according to standard practice to avoid misunderstandings, MSRP or not since it is a luxury line carrying the equivalent of Capone's protection insurance when placed in the hands of ambitious business men and employees without major scruples.
No offense but your suggestion does not make any sense. I am not complaining about the car's quality here. We are talking about the dealer's service. Just because you are not happy with the dealer, you do not change your brand. You stop buying the brand if the product is not what you expected. In this case, you just stop going to that dealer. Period.
