That's precisely how people figured out more were made than claimed.
Rolls Royce values drop to 30% of new the day they come off warranty. They don't care about depreciation, once a car is sold they made their money. McLaren is the same way.
Owned a Cullinan and lost 5% after two years and could have made 5% if I took the time to sell on my own vs trade in. Few weeks ago bought a Dawn Black Badge and can sell it for 50k or more over msrp. To address the 30% off warranty - a lot of that has to do with corporate leases that get turned in and those companies actually made their 30% by the Gov't deduction on a car that slid under the farm equipment SUV weight category. My guess is most made above the 30% vs lost it and enjoyed their vehicle.
Rolls does care - they offer trips Monterey and many other ways to make you feel part of their family - cars for some is a lifestyle that owners buy into and when pulling up to their 20m jet or 100m yacht is - just something they do.
Mclaren also cares - I got whacked by a cowboy salesman and Mclaren mgmt. stepped up and secured me an LT Carbon edition to remedy.
You and others are certainly entitled based off your experience - totally fine but others including myself have a completely different experience.
As far as Ferrari and their past - there were games but once public and got caught all issues were addressed and there is zero tolerance for games of allocation etc.
Ferrari in Vegas - canned as were many others. VIN numbers are heavily watched - when a car arrives at Port it's run thru the ringer and then some - Porsche got caught the worst and paid not only fines but jail time.
I'm simply saying - buying cars is an investment in time and money and how one wishes to treat that investment has a lot to do with the result / sale.
Going back to a lot of wasted time on the Ferrari debacle of more than stated - my 16M was actually lower as Ferrari shuttered in 2009 due to owners and dealers cancelling orders. The 599 Aperta and a few others seemed to be a problem but after many hours days weeks years it was less than 20 or so and that wasn't even proven. Keep in mind Enzo hated customers and it was all about the passion to race finish and place. For fun watch Carroll Shelby in action when he told customers to go f themselves and nearly went broke doing so as did Enzo Lamborghini many times and Aston I think 8 times has declared bankruptcy.
The old guys didn't care about anything but winning and they didn't go home at 3:30pm it was more like 3:30 am - todays bean counters and stockholders and Gov't are far from the engineering racing mentality of extracting everything they had to perform. Mass production ROI these words never entered the early exotic factories but now that they have it's a rare gem that reflects the past and there aren't imo many more to come as most of the great ones have already been produced.
Anyway - expect what saved Porsche to arrive soon ... one more Mac (suv) on the dance floor.
