I think the Cayman is really the last good canyon carver that Porsche makes, but it's really bordering on too much for that purpose. That said, the change to a flat four on the 718 models already has their used values falling pretty sharply. In 2-3 years, I imagine really good deals will be possible there. The flat six in the GT4/Spyder is pretty awesome, but those are silly money.
I've got a '19 ND2 myself, and it's what I'd go with every day if you want the best bang for your buck. They're stupid cheap to own, and there's no substituting the small size (if you fit) and low weight (even the RF only tops out at 2400 pounds). The revised motor is really sweet too (there's a very Honda-like crescendo getting to the 7500 RPM redline). Plus the aftermarket for Miatas is nearly endless, and only seems to get better with time.

Now that its confirmed that the next gen BRZ/86 will arrive as a 2022 model, I'm waiting to see what those are like. I love my 86 and if the next gen is an improved version, I'll definitely want to test drive one. Nobody seems to know what motor it will have...2.4 NA, 2.4T, 2.0T..... guess I will wait and see.
RF ND2 w/ BBS/Brembo package is also up there on the short list. It would be Miata #5 for me
