I heard 'ID.3' and 'speakers' so this seems like a thread for me!
First on general "is it a good car?" stuff... what you have to bear in mind with the ID.3 is that 1) it is a fairly radical departure from the 'norm' in some ways, and 2) the early software was abysmal. Those things have combined to mean there's a lot of hysteria about the car floating around on places like YouTube car review channels.
On my point 1 - you yourself have said that other cars you might have considered competitors are way more expensive. The other options you have listed as being within your price range have smaller batteries. How are VW selling long-range EVs (with a lot of new tech in them!) at such a competitive price point? Because they have clearly taken a long hard look at where to spend money on materials, etc. and where not to. They have obviously decided that EV buyers are more likely to prioritise clever technology like matrix headlights over wood interiors, and lots of leather all over the place. For me, they were right to make that call. For you? Only you can say. But if you want both things, you'll have to spend more money and get an Audi or something like that.
That said, I personally like the interior design overall. It seems light, spacious, minimalist, modern. It definitely matches my idea of what a stylish, modern interior is. But everyone's taste is different.
There are other calls they made that are just new, and different, and YouTube reviewers who jump from car to car to car clearly don't like that. There's a lot of emphasis on what is 'intuitive'. Well, the most intuitive way to do car design is to never change anything, but that's not really progress is it! Cases in point,
- Rear windows button - YouTube reviewers scream about that being unreasonable cost cutting. I think it's genius. I was forever accidentally opening rear windows in other cars, but in the ID.3 I never do. Times that I actually do want to open the rear windows from the front (which is never), it is just one additional button press.
- Steering wheel touch controls - are they as intuitive as physical buttons when you're a YouTube reviewer who only has the car for a couple of hours? Maybe not. But they are brilliant! It is so much more functional once you realise that swiping and tapping do different things and learn that. It'll take you a week or so to figure all that out, but then it is so much better.
- Volume/temperature sliders - as above. I can control music volume with one fluid hand gesture without looking at this point. So much better than old fashioned volume knobs once you get used to it.
Ok, now onto point 2 - almost every YouTube review you see was done with a car on the original software. Hence the infotainment seems horrible, laggy, fault-ridden because it was. Even for newer YouTube reviews, I think it has become so accepted as 'fact' that the ID.3 infotainment is horrible that reviewers go into planning their review thinking "oh yes, I must mention that the infotainment is horrible, because that's one of the essential things to do in an ID.3 review" before even trying it for themselves. FWIW, I think the infotainment is great! Best I've ever had on any car. Wireless CarPlay is a game changer too.
This isn't to say that the ID.3 is entirely fault free yet. There are still forum reports of issues here and there. But there are for most cars. Certainly the ID.3 has come on leaps and bounds since the early software builds and I know that my own ID.3 has been fault free and dependable for a while now (despite being a former problem child on the early software!)
Finally, onto my signature topic on this forum. One of the areas where VW seem to have cut costs that did bother me was in the audio system. Lower-to-mid spec trims don't have rear speakers at all. I also found the front speakers that it did have caused a lot of vibrations at louder volumes on bass heavy songs. If you just like casual music listening or spoken word while driving it will be fine. But if you're really into music, I think you'll find it disappointing. I remedied it for myself by sinking over £1,000 into an aftermarket audio upgrade, and it now sounds amazing.
Ok, that was quite long wasn't it? I think I'll go lie down now...
