it is until random stuff breaks as it gets old.
The passenger door handle/lock is known to have cable stretch, which used to be $20 part. But Ferrari no longer sells the cable by itself so you have to buy the whole door lock/cable assembly for like $800. I grabbed a cable from Maserati and it's sitting on my storage shelf.
The 2000+ cars have a pre-cat in the header collector which has come apart on some people's car (it's very rare) but it does happen. This can get sucked back into the engine and cause catastrophic damage.
The carbon brakes are crazy expensive but folks have found that certain model year Vette's have the same pads/rotors and a much cheaper.
Clutch components are not cheap and the F1 cars do not last as long as the manual car. That can be $10k all in if you pay a shop to do it. The clutch, flywheel, throw out bearing, etc is $4,000.
Just random stuff like that on the older cars can bite you. They only made 15,000 360's. It's not like there is a crazy demand for parts so they get expensive.
