I think most people would be hard pressed to come up with a mil for 2, so that's only 40k. For 2 people that would not be anywhere close to enough even in the boonies. 120k isnt really that much, assisted living is something like 5-6k here so you need 1.5m to just cover that without other expenses.
I dont know why they would choose 200m deep, its pretty dark at that depth and not super interesting. Why not park it somewhere near a reef at 30-50M, dive in dive out experience for tourists, good vac options, good lighting and easy to work on.
I personally really had the USB C "Standard". The cable shape and fit is good but the fact that the different USB C cables all look the same but dont actually work the same is a real problem. Having identical looking cables without any markings on them to indicate capability is really problematic.
The ford 10R80. 10 speed transmission is famous for being terrible dispute being in use since 2018.
As for toyota their new engines and transmissions arent really any better for fuel economy but seem to have reliability issues anyway. I think its more of a problem of too much power as the HP war rages on for more powerful engines.
