Hypercars are economic hazards by design.

More so when you spend nearly $600k on a salt water damaged one.

But then again, they seem to earn a decent bit of ad revenue from people wanting to see other people spending absurd amounts of money on money pits, ironically making the money pits a viable business model.

This why I miss the old parts shops that used to be around. Look up part from the main dealer and its £100, go to parts shop and they look at it and rummage in a box and find one for a tractor that is only £2.50. Many hyper cars use standard parts for easy stuff with just some special bracket to make it annoying.

Seen a few of these buy and crashed car and fix it up type things. The money to buy the wreck is still scary and it's quite a gamble. Some of the vids it's clear they just get somone else to fix it they just video it. Fine if you have money to waste.

Mechanical stuff is not hard, even if you need to fabricate an entirely new part; it's usually the electronics (proprietary parts) and software that causes the most problems.

I'd suggest checking Tavarishs' secondary channel as well.
He had a talk with "V engineering" in UK, who happened to have redesigned the main P1 drive battery (in cooperation with the people who designed the original battery). The original battery seems to fail a lot.

Rich used parts from the original (now bankrupt) manufacturer, just a little bit less capacity. And even though he hacks things together, he does amazing work.

Btw. other manufacturers offer Li-based batteries as well, and those are thousands as a replacement part as well. Multiply by factor 3 for "supercar" :)

I remember tales of hyper cars using infotainment systems from BMW etc just with modified boot up images.

Mechanical stuff is an "easy" some of it is still clever stuff it's just a shame when it brand change and sold for mega money. A temperature sensor for a Triumph Daytona £68.99, same sensor for a DAF lorry £2.50. Don't get me started on Marina door handles as once you start to see them you can never not see them.
