HV Battery State of Health (SoH) - what to ask before buying

Agreed. To me, the SoH is not something to be scared of, it's just another thing to check like the car's mileage. Some people like buying a 2k mile car instead of a 12k mile car. The 12k mile car is likely much closer to needing new brake pads, new tyres, etc. It's not like the 12k mile car is a bad car, it's just likely closer to needing some work.

A 70% SoH HVB car is probably closer to the point of getting errors and needing a new battery than a 95%. But that doesn't mean the 70% is "bad".

Agreed with all this. As well as being aware of the HV and LV battery SoHs another significantly expensive consumable in the car are the ceramic disc brakes.

When you ask the dealers about ceramic disc wear they will want to fob you off with "xx millimeters left on the pads" type of comments. The concern is not the pads (which are cheap) but the ceramic rotors (which are expensive). The state of health of ceremic discs depends very much on how the car has been driven, not so much by age or mileage. Clearly if the car has done lots of track days then this will rapidly wear the discs. But also if the car has been driven a lot in "wet" mode this also speeds wear of the discs, particularly on the rear.(Note: Don't leave you 296 in wet mode when it isn't being driven in the wet).

One obvious way to tell if the discs are shagged is to feel the surface texture: if they feel unusually rough or pitted then be careful... get them independently checked as they are probably shagged. I did see one car on the market during my search with discs like this... probably lots of track days. The discs are not thinner, but the resin binding the ceramic has worn off. But it is not always obvious by looking at them or touching them. One way would be to take the rotors off and weigh them but this is not exactly practical. So Ferrari also have a disc health metric calculated by the cars ECU that takes into account cumulative wear, brake application force, temperature during use etc and spit out a % figure. You can ask dealers to get their techs to find this number out too when you screen for good cars.

This is common to all CCB equipped Ferraris but perhaps a little worse because weight and power?

I had to replace the CCBs on my 458 and it was a wallet shock.

Mind you I have never used Wet mode.

Wet means not Race.

James, thank you for making the video on Ferrari hybrid warranties:
