Long story, short and short: Last month an Opel Grandland Hybrid Bj2021 with 30ktkm looked at at the Opel Autohaus. – Technically comparable model was allowed to test driving because the other probably was not “ready” Binding order was promoted to me as “purchase contract” whereupon I had to pay the number, so that the car dealership can make the car “preparing & TÜV”.Told: Paid & the next day also transferred the “full sum”. ÜV certification came by post and we have registered the car. I was informed that an error in the flashing system would be reported and that a controller would have to be replaced here. On the question that a TÜV certificate exists here, it was said that this was not noticed by the TÜV. However, the workshop was already informed. Question about replacement cars was denied that the car was still “not at all” delivered and therefore no replacement car was required. After we finally found out what we did wrong in the trade here, we realized that the “binding order” was not a purchase contract. A down payment and completely pay it would have needed “not”. After “bad” letter and turn on from Opel parent company: the car dealership was very accommodating to make a replacement car. But we are still in the “dark” when the car actually bought is available. quite great is yes: that if d he wants to withdraw from the purchase: then the dealer can withhold 25% of the sum. How do I turn the spikes around ? Delay of delivery, damages or… 2 weeks later it came to the replacement car ….. only that is not the purchase object I even assume that a delivery will not be “possible” due to further “technical problems” When “must the dealership” step back from the purchase ?
