Ferrari California/ Porsche 997 Turbo

Hello dear Porschecommunity, does someone from the forum have experiences with the Ferrari California? This is in the meantime relatively(!) cheap available and I read that the maintenance costs should not be too high. Does someone have accurate data about this? Consumption is about as stated as with the 997 Turbo I (13.8 liters). But now you can drive the turbo between 8 liters and 26 liters/ 100Km. On average, with quite high land road share around 13.5 liters. Is the vehicle sporty with less than 20 liters in high road parts? I read that the Ferrari only needs Super, but can’t imagine it. Does anyone know what to do with it? Inspections are every 20,000km (?). Costs? Can anyone give me explanations about Ferrari’s power guarantee? (cost? runtime=max. 10years?) What about the wear and tear when driving relaxed? Similar to Porsche or do some things have to be renewed more often? Turbo has already 305s on the HA. What about the Ferrari? And lastly on the topic of insurance. The Turbo is far from cheap. Is the Ferrari so much more expensive? Thank you already in advance. Greetings P.S: I am interested in the information. I do not plan the purchase of a Ferrari. P.P.S: Please only serious answers and no hostility. Do not feel like a kind of thread as it was often observed last time. If you just want to provoke, bi I wouldn’t write anything.
