There are also new European rules about noise so next models will be quieter. I’m sure California will follow.I'm going to play devils advocate here and say the hype about the A been the last NA V12 model doesn't matter short term. Hear me out...
We all know the replacement will still have the V12 but with hybrid assist so technically the V12 is still going to be around. We assume the replacement will be heavier but what if it's lighter? And we assume the exhaust note will be muted, what if it's not?
Maybe we're all in a NA engine bubble thinking the market cares and A values will shoot up once the replacement is announced but we all know most buyers want the newest and craziest supercar which is why I think there is a strong possibility the used A market takes a big hit once the replacement is announced. There's always going to be A owners including the owners of the SVJ and SV who don't care about NA engines and will start dumping their cars to get into a replacement.
My point is be careful and don't overpay for any A model because there's a good chance they'll be a dip in the A market once the replacement is announced.
