Honestly, this is a non biased post.
I have my truck, I have a Mercedes A220 as a fun/sexy car, but that isn't so expensive for a German luxury car. Honestly, I should have picked up a Tesla Model 3. I was test driving them for a few months at different areas, almost bought a used Model S at Covert instead of my Ram. Now, I wish I picked up the Tesla over the Mercedes
The convenience factor is merely a change. If you spend $500 and get a semi supercharger in your home, then your home is a gas station and the habit is just like charging your phone, except you need to do it only on long trips or once or twice a week (for my daily driving). I factored all the overall costs of owning one and it's actually far cheaper than both the RAM and the Mercedes just because of fuel costs. I'm getting ready to move to California and wish I had it more given that EVERYTHING there is super expensive which makes this much easier on me. Maintenance isn't actually as bad as what people make it out to be. A lot of people rag on luxury cars breaking down and how 'expensive' they are to maintain. Yeah, that's partly true, when you take it in, it's definitely more expensive.
My Mercedes only needs to be taken in once a year, for anything except maybe the tires. My Ram needs to be serviced about what, once every 4-5K miles for an oil change. In my area, Tesla comes to you for service and you can get the first few years included if you don't order online. Which the whole experience is a no-frills and no negotiating etc. You get a simple APR if financed through them and a simple price.
Does it have its concerns/problems, most definitely - but I really like the market they're pushing. No gimmicks were anywhere other than the marketing of features that aren't what they are all out to be. But as a daily driver and the awesome OTA updates, it's pretty cool. The rear seats of the Model 3 can fit 3 adults actually. Instant torque for passing in lanes was great. Autopilot is light years above our Lane keep assist.
I live in San Antonio and the heat is brutal. They have a dog mode where the vehicle still keeps AC on, but it's not really running and puts a big sign on the 15" screen that the dog is fine, AC is on etc.
The experience isn't exactly German luxury by any means, but it's better than most all of any other competitors. I picked the Mercedes for the name, for the luxuriousness and the interior/exterior experience. My vehicle has the new MBUX infotainment and it's basically Siri/google in your car, controlling your vehicle's functions. Also has augmented reality for navigation where the camera pops up and shows you EXACTLY on the road you need to turn and it's super accurate.
Most of the American vehicles for infotainment are gimmicky or just very lack-luster. I loved my 12" screen in my Ram, but using it was not intuitive and mostly for the "wow, look at my screen" ego rather than practicality use. Navigation was useless by voice unless I knew EXACTLY the address I needed, or I had it favorited.
In the MBUX system, I can just say "Mercedes, navigate to the nearest Best Buy" and poof, does just that. Or I can say "I'm craving Thai food" and it'll come up with a list and you say which one you want.
I can tell her to open the sunshade, turn on/off the reading lights, ambient lighting, ask fuel consumption like "How many miles do I have left on my tank" and poof "You have 226 miles left before fill up"
The maps will show when/where it's raining, temperature, gas prices for my actual gas price (premium/93) and it's all up-to-date.
I really want a Rivian if the driving experience is as good as Teslas and offers somewhat of a good polished experience with infotainment because honestly, this is where the American market sucks donkey at.
Sorry for the long post lol, kinda rambled there
