I like Barron's , especially regarding things that aren't new. But with new things (tech, Tesla, etc.) that's like asking my Grandpa about social media platforms. "Rich" people tend to be older people, and older people tend not to like change very much, so I think they tend to stick with things they understand, rather than these new crazy electric cars that catch on fire, have low demand, etc. The model s is pretty much the best all around car you can buy right now, competition isn't going to suddenly make it obsolete.
