I think Mazda generally does a good job with refreshes. The only giant fail I can think of is when the 2000s Mazda3/Speed3 was "refreshed" and it was hideous. The earlier ones look perfect. Very French looking. Mazdas design language in general is super nice now. I appreciate that they make driver's cars across their whole lineup, but in the end it's a Mazda that will start to fall apart at 100K miles even if you take care of it. I've owned a couple. Miatas might be somewhat the exception to the rule. But my NA still looked classic at 190K despite the paint peeling. German cars seem solid for a long time IF you put money into them. Toyota rules for cars that last without breaking the bank.
That said the picture above (and I skimmed the video) is more what the NE will look like. I wish the current ND looked more like that and not so busy. It kinda works better on the hardtop but those get so expensive. The NE could be a fail because of the possible hybrid powertrain. I'd rather them just go all-electric if they can't do it right. The ND could be it for classic RWD, ICE, manual Miatas. That's why I need to get a GR. It will the absolute last of a classic layout.
