I'm gonna say yes, then tell you why. So, Yes.
Why? As a subjective personal matter, nothing works quite as well for me. I know that's the kind of voodoo BS that Leica people like to toss about, but I've tried to kick the habit a couple of times, which has cost me a fair bit of cash, and found that it really is true - for me. Since this is the internet, I can say YMMV.
My first "real" camera (after an Instamatic 44) was an M3 that I saved and saved and saved for and purchased used in 1972. In the 1980s I bought several more bodies, a large number of RF lenses and several Visoflex lenses. In the early 1990s I thought I really needed something different and sold almost all the Leica M gear - kept only my original M3 and a very late Dual Range Summicron. In the early 2000s I really wanted to get back to using the M cameras and bought an M5. I read and talked and really thought (and still believe) that the M5 is an objectively better camera than anything short of an M7, and might be better than an M7 in some ways - but I just couldn't get used to the size and shape of the body and the location of the controls. I recently sold the M5 and now have three Ms: my original M3, an early .72x M6 and a .85x M6 (a classic, not a TTL). The .85x is really intended to be an M3 with a meter...
Why do I keep selling and replacing? Because taking pictures is not entirely about the images. It's also, for me, about the experience, about how the tool fits and works. And, for me, the classic Leica body is just the right tool. So I'm done with the buy/sell/buy cycle, the ones I've got are keepers now.
You might not agree, or you might agree, but if you buy smart you can probably find out without a whole lot of risk - you should be able to sell for more or less what you invest, at least if you don't overpay when you buy and don't trade to a dealer when you sell.
For a car analogy, I think the Ms, at least through the M6 classic, are more like an MG-B than an Aston... 😉
