Really the most satisfying overall is my Model S Plaid, but...
For memories and sheer exuberance it was this:
I do not have a photo of mine, but it was identical to the photo above.
For an ICE there is nothing to match a tiny four cylinder needle-bearing 11,500 RPM redlined built more like a motorcycle than a car. I loved that and drove it all over Thailand and some of Laos back in 1968 when I owned it. It replaced a Honda motorcycle. I saw it in Bangkok where it was being prepped for delivery to the Honda GM's spouse. I went nuts and he graciously offered it to me, perhaps influenced by the initial arrival of cars other than the N360, itself a blast to drive.
Shortly after that somebody told me there were things called ADR's (American Depositary Receipts) that Honda had that allowed foreigners to buy shares. Clueless I was, but I tapped my tiny reserves and bought some, thinking those motorcycles were pretty good (I'd ridden a Honda Dream back in the USA years before) and the cars were sooo much fun.
Those shares worked out, I sold my S600 when I left Thailand, I never have forgotten that wondrous tiny exciting car-like conveyance.
Despite those memories and those of Morgan, Ferrari, Maserati, Porsche and many more...none ever matched the sheer glory of that tiny, tiny car that felt so very fast while never challenging any speed limitations. Those feelings never were matched by any other car. I felt the same about a Learjet 25D, but that is an entirely different story and does not even come close to the S600, albeit being much, much faster and much, much more demanding for the operator. No qualification was needed to be captivated by that Honda S600.
Now back to my Model S Plaid which simply works, in a mature and responsible way, while still having the potential to out-accelerate that Lear, at least for a quarter mile or so.
