I've owned a gen 1 NSX and a gen 2 (AP2) S2000. Your assumptions about the soft top/vert are correct. It's loud, is a liability parking it somewhere out of sight (thievery). The loud part I got tired of with my S2000. The cabin is also cramped (the Miata is also), and I just don't like the inline 4 motor unless it's a crossplane. The S2000 was/is a great car but the hype exceeds reality. I haven't missed mine since I sold it, not for a single day. It was great at the track, and on the road, but the -'s outweighed the +'s.A few days ago, I knew very little about Miatas other than they were cute, little, impractical convertibles that didn't have much power, but handled well and were a blast to drive. I've spent the last few days studying Mazda's website, watching reviews, reading forums, and shopping.
I knew early on that I didn't want anything less than the Club (middle) trim because of the lack of an LSD. I also knew that I wanted automatic climate control which only comes on the Grand Touring (top) trim. I then realized that the Grand Touring deleted the LSD which led me to shopping for a Club and giving up some other options I wanted. In my opinion, Mazda's website can be misleading to someone who isn't well-versed in Miatas because it doesn't disclose that the Grand Touring loses the LSD (as standard). Fortunately, I discovered that it can be re-added with the GT-S package. When I mentioned that I wasn't too fond of convertibles (due to noise, leaks, maintenance, and security), I was asked why I didn't consider an RF (retractable fastback). At the time, I was under the impression that the RF was a lot more expensive than the soft top than it actually is.
Those considerations are what redirected me from a soft top Club ($30K) to an RF Grand Touring GT-S ($35K).
I will likely hold on to the 2019 Ridgeline for two more years until the B2B warranty is up. By then, the G3 should be out. I've certainly traded for lesser reasons, but I've not yet seen or heard enough to convince me to trade for a 2020.
If Honda still made the S2000, I might have been able to stay in the Honda family.
I really enjoyed my 2017 Civic Si and lined up to buy a 2020. While the Civic Si is certainly more practical than a Miata, I already have one of the most practical vehicles on the planet - a Ridgeline, which will continue to be used for weekend shopping and road trips. The Miata is also 2.5 feet shorter than a Civic, so it'll fit in my garage with my Ridgeline, scooter, mower, work benches, etc.
The GT-S package restores the handling bits from the Club that the Grand Touring loses including stiffer springs.
I enjoy driving or riding in convertibles (during a very narrow set of weather conditions), but I've never been eager to own one due to the issues mentioned above. The BRZ/86 just don't do much for me. The RF solves most of my concerns with a soft top while still offering more open-air experience than a sunroof during nice weather.
The PP Equipped BRZ is an extreme value. You're a wise competent shopper, you can steal one right now. PP gets larger rotors, Brembo calipers and Sachs dampers that are on bar with Bilsteins, just a smidge below full Ohlins. I believe the wheels are different as well, half an inch wider. The cabin is better, to me, as there is ample room for smaller and larger drivers and you've got some cargo room in the hatch, enough for groceries, golf clubs, or weekend luggage for an escape. For a 2 seater or coupe, it's got the best driving position of anything affordable on the market today. It's an instant classic, a car that could be kept for many many years. DI+PI = no issues to deal with going forward. It's built in Japan and worthy of all the praise it gets. Even if it is not wetting your noodle, go drive one for grins only. Any dealer will toss you the keys. You only need to take some bends in it, any decent turns and you'll understand. The performance package is like $1195 so the car can be had for $30k. An old boss I had just went through the same thing and was dead set on the ND2. He went and drove the PP BRZ and called and said he bought it and thanked me as it was 5k cheaper. Subaru holds their value better than anything out there should you want to trade/sell in a few years. The chassis in that car is so competent that I call it a Cayman - the motor. At 35k, that changes things as you can grab a used Z51 C7 for 40k, and have 455 HP, and monster capability.
