Hello, I’ve been fluctuating for a long time between a used Porsche Panamera and a BMW 6’er. But the initial purchase prices at a Panamera are easily 10,000€ higher (with the same year of construction and mileage output). In addition, higher spare parts prices etc. So I ended up at 6’er again and prefers to be a convertible. For cost reasons I would probably want to take a 640i (320 hp) from Bj 2012 or 2013. But you can also find a a very decent 650i for hardly any more money. Now my question: From the 650i with 408hp I am always strongly advised not to. Many say that one can almost be sure to get an engine damage. The engine is probably mega sensitive. To this one also finds many (negative) contributions in the net. Can someone tell me what it looks like with the 449hp engine? Is actually also the N63? Does the engine have such a reputation?
