Dealer inspection vs independent for a Ferrari, worth the difference?

I'm in the middle of negotiating on a California T and the seller keeps pushing me to just use the official dealer for a pre purchase check, but the quote they gave me felt pretty steep for what seems like a standard diagnostic. A mate of mine reckons an independent specialist is the way to go because they actually know these cars inside out and won't just plug in a computer and call it a day. I'm torn because part of me thinks the dealer stamp might be safer, but another part wonders if I'm just paying for the name. I ended up on a page about Ferrari inspections in the UAE and it broke down what a proper check should include, stuff I hadn't even thought about like clutch wear readings and suspension bushings. I wanted to learn more about how they actually compare to a dealer report before I commit, so if anyone has been through both and can share what the real difference was, I'd really appreciate it. Not trying to cheap out on something this important but also don't want to get fleeced.
