I have my own opinions but curious what others think in regards to...
Is it an automotive company or tech company?
Stock evaluation. Is there still upside as it has low revenue and high evaluation?
Vehicles offered, quality, all around capability/performance.
Think Apple will or Toyota will blow them out of the water with technological advances or offerings?
Tesla stock is greatly overvalued, but that's the stock market and it sometimes doesn't follow logic.
However, as a car and their technology, it's probably second to none in their field. Apple (no way they are going into cars) and Toyota or any big manufacturer are on the back foot. There are key electronic parts on Teslas that would take 5-7 years for mainstream manufacturers to catch up to. A lot of this is based on legacy car builders being economically tied to their component subcontractors that Tesla isn't. They can innovate daily in ways they cannot.
The same company who broke down an early build Tesla 3, and criticize it's build quality to a 90s Hyundai also stated the electronics were simply on another level and couldn't believe how advanced Tesla was. The build quality is getting better, I've seen plenty of examples that seemed to have excellent fit and finish. But their ability to do over the air updates is vastly better than anyone else. Look at RAM, we all want Uconnect 5, but will have to buy a new truck in 2022 maybe to get it. If it was Tesla, you would simply wake up one day and have it there due to an update overnight.
Then there is their supercharger network, which is again 2nd to none. This is a big reason why people who want a daily driver EV buy them. They have the infrastructure to support them. Every major manufacturer so far that has produced a Tesla "fighter" hasn't come close in terms of sales. The Ford Mustang Mach-E is probably the closest one so far, speficially against the Model Y, but again weak charging support for truly everyday usability compared to Tesla. Interesting to see how well it will sell.
