Regarding my question, my friend treated his BTC as if they were real coins, and assumed that their legacy status could one day make them more valuable as "collector's items". The thing is, with real coins, you can sell a rare, old coin at a premium and you can transfer ownership by physically handing it over to the buyer. With Bitcoin, the equivalent would be to give the buyer the private key, which you also know (and cannot guarantee you won't use), so it defeats the purpose -- the buyer can never really be the sole owner of the legacy Bitcoin (unless s/he kills you, or uses a Men In Black Memory Eraser on you, and still there could exist backups accessed by others).

About Toyota vs. Honda, I also would choose Toyota over Honda, although Honda engines are supposed to be of very high quality, especially the motorcycle ones, from what I've heard. I'm eyeing the latest CH-R Hybrid -- will probably be my next car. Was keen on getting a Tesla, but it has lost some of its appeal to me for ... reasons.
