The idea is that you buy several normal cars from them, then, if you are lucky and really, really on best behaviour, they will let you on to the lottery to get an allocation for one of their special edition models.
If you get the special allocation then you can't 'flip' it, you have to play by the game because otherwise Ferrari won't sell you another special edition model.
If I was a dealer and I had to replace 1000 fuel filler widgets free of charge in my own time in order to keep those customers happy enough for one of them to come back and spend a million, then it would not be a problem. Getting those 1000 customers through the door again (or even a dozen of them) is all good.
Funny how few of these Ferraris get to put in any miles. It isn't range anxiety, it is mileage anxiety. If you had to drive 400 miles you would not do it because of the miles and how that affects the value. Hence these cars spent their time in garages, connected to wall chargers, turning a wheel once or twice between services in order to ensure everything is mechanically peachy.
In the UK the likelihood of finding a Ferrari is high in London where the average speed is in the single digits. Some of these cars don't get to escape the capital, they don't drive at speed, they just sit there as a speculative asset.
Even for high end race cars, tyres you need to pay out of pocket for - since they are total wear items.
The car dealership is doing work under warranty, so they don't make any real money from you (they can put in the work/time/labour for whatever the manufacturer wanted them to fix, but that has a set margin that's determined by corporate - who for sure have counted their beans) - the real money is in upselling - getting you to do brakes while you get the warranty repair done, selling you new windshield wipers while you're there, etc.
Hey while you're in for servicing, why don't we do a fuel system treatment too? it's only $50 and we'll get your car fixed for the warranty and get it to run better too!
The other side for car dealership warranty repairs that I've also seen is that they get so many repairs in the shop that they can't do each one properly cause they are under pressure from corporate to do the servicing for a certain dollar amount, and they can't spend any additional labour hours/time to do it right.
this happened on engine recalls, due to the complexity of an engine recall, the mechanics didn't get allotted enough time to do each one, so basically, corporate tried to shove 4 hours of work into 2 paid hours - the end result is shoddy workmanship due to the mechanics only doing 2 hours of work on a 4 hour job (so rushed, loosed bolts, parts left over, not installed correctly, etc) - there ended up being a 2nd recall on top of the first recall because it wasn't the dealer mechanic's fault - they weren't being given enough time to do each one
