Yet many owners manuals state to keep revs and load low for the first 1000 miles.

McLarens are still faster so this car, while nice, seems unimpressive to me.
Especially if it falls apart.
Or leaks/burns oil, has bum rings.
Or all of the above.

Ah the never ending break-in method debate. Some load is required IMO. You can put a decent amount of load on an engine without revving the engine too much.
His oil consumption is a quart every 2,000 miles.
Honestly, that isn’t bad, it won’t smoke or cause problems.
While I am a fan of HPL, I don’t know that there is much that can be done to solve the oil usage on this car. I don’t know enough about this engine.
Without knowing more about Ferrari ring specs, PCV systems, valve stem seals, etc, it’s all just idle speculation.

I was off on my statement of his consumption rate. More like a quart every 500 miles.
Still not enough to cause visible smoking.
With no leaks, it can only be going out the tailpipe, but it’s ot clear whether it’s getting past the rings, blown into the intake by PCV system, or leaking down the valve stem seals, which are the common ways for oil to run through the engine.

Complains about Ferrari reliability but mentions McLaren who are well known for being one step above garbage
Not to mention resale value

Why not both?
I'd rather have a Toyota, I am not sure I'd buy a new Ferrari if I had the $. McLaren.. I could buy about 30 cars.
But this thread isnt about me. @AEHaas has the vehicles.
Folks, let me add, that if you threaten another member, you’re gone.
Your posts will be deleted.
That is simply unacceptable behavior.

Is this the same guy who was trolling everybody with incessant use thin oil posts now complaining about excessive consumption? Or a doppelganger that is curious enough to ask folks why his $330k car is not happy with his choice of viscosity? F1 cars used to be able to burn lubrication oil as fuel. Perhaps that is where your oil is going.
I do not think so.
70-800 HP mills needs room for the expansion that happens when you put out that much power.
A manufacturer (at least the ones I deal with) needs to move from hyperutectic castings to forgings that run loose until you get heat in them.

It doesn't have stuck rings and it doesn't need engine cleaner. Many high performance engines consume oil, it's normal. The BMW S62 was incredibly prone to it due to low-tension rings, so much so, and it garnered so many complaints that BMW upgraded the rings to improve the situation. This is the pre/post 03/00 situation. The pre 03/00 cars were spec'd for TWS (10w-60) while the post 03/00 cars in most of the world were spec'd an LL-01 oil.
Dave runs spec visc in his high performance vehicle, I doubt he'd be telling Ali to run 0w-30 either. This is kit you don't want to be footing the bill for, nor advocating/providing advice that could cause damage or failure.
the 4.9 V8 was not really a high performance engine.
everybody and their grandma were starting to pick up low tension rings back then, even the econobox vw 2.0 had teething issues with them

For the period it was reasonably high performance, particularly being fitted to a sedan. 400HP; 81.6HP/L, the Mustang Cobra was 69.56 and the ZR1 Corvette with the DOHC 5.7L was 71HP/L.
Of course the V10 that came after it was even more power dense, but we were into the 2000's by that point. The E39 was a mid-90's car, and, for the period, the performance was impressive. Even the Lamborghini Diablo of the same period was only 85HP/L, and the Testarossa, which ended production the same year the E39 M5 was introduced, its 4.9L V12 produced 385HP, 78.6HP/L.
IIRC, it wasn't just the low tension rings, but also the fitment of them to alumasil bores that proved more problematic on the oil consumption front. My '01, being a post 03/00 car, consumed very little oil; ~1L/12,000Km, while one of the ones I test drove was a pre-03/00 car and it drank 1L/1000km.

Problem solved. I was looking at the parts diagram and saw that the breather tubes off the top of the oil reservor were at about the same level as the Full mark on the oil stick. What I found out was that the oil level was stable when it was an inch below the LOW mark on the stick. In fact over the following 1,500 miles there was no change of the oil level at all.
I then decided to remark the oil stick. The original MAX mark was removed. I relabeled the original MIN mark as my new maximum. Two inches below the original MIN mark I made a new minimum line. I also found that the oil sat about a quarter inch onto the bottom of the stick when the oil was cold and the car sitting there a few days.
I am now several hundred miles into the RLI grade 0W30 motor oil. No change in the level. It is steady an inch below the original MIN mark - an inch below my new relabeled maximum mark.
I believe the Ferrari dealership, who has followed my work, has told their technicians of my findings and adjusted to my fill level when servicing the 812 SF cars.

Some pictures:
Are we to conclude that the people who designed and manufactured the $400,000 car didn't correctly mark the dipstick and/or dealer(s) (one local or all?) are going to take a huge risk and "adjust" the engine oil level without consulting the manufacturer?
Even IF you are correct and have discovered a problem or an issue, I assume that the directions (TSBs?) would come from the top.
With all due respect, this is a blatantly implausible claim!
btw, I would fire that dealer even if you were correct.
