Hello, I had been smart about a 6′ convertible F12 (from Bj 2011) in the forum for a long time. I was advised against the first 650i with 408hp due to engine problems. The 449hp is supposed to be much better, but is probably still more vulnerable to the 640i (even if it is more fun of course). Is that your opinion too? Otherwise I would like to look at the following three driving lines (see 1, 2 and 3). The 2nd 640i of course did not run very well, but rims are not very good. What do you think about it, which one you would recommend to me and what should I take care of/check on with the three? 1.) 640i: Vehicle data: BMW 640i Cabrio HUD Camera ACC Night Seat ventilation Heating German vehicle 2.Hd 31.999 € First registration: 08/2013 Kilometer level: 129.999 km Power: 235 kW (320 hp) Color: Silver Metallic Click on the link to get directly to the advertisement:https://suche.mobile.de/…/details.html?… 2.) 640i Vehicle data: BMW 640i Cabrio*Navi*Camera*2-Hand*German vehicle 35,950 € First registration: 11/2013 Kilometer level: 81,700 km Power: 235 kW (320 hp) Color: Silver Metallic Click on the link to get directly to the listing:https://suche.mobile.de/…/details.html?… 3.) 650i: Vehicle data: BMW 650i Cabrio xDrive M-Sports package LED ACC Standh 35.900 € (Brutto) First registration: 05/2013 Kilometer level: 128,900 km Power: 330 kW (449 hp) Colour: Black Metallic Click on the link to get If you are looking for an advertisement:https://suchen.mobile.de/…/details.html?… I find that the 650i engine causes a bit of grumble in my stomach and is also a bit expensive in the maintenance (consumption, insurance, tax). Unfortunately, it is also further away from my place of residence. But I would like to know your opinion or also get tips. Would be super nice. Because at least the 1st 640i with about 130,000km I look tomorrow afternoon.
