Honestly, I am a big fan. If we actually get that version stateside, I would be interested in buying with or w/o a manual.
I also believe (based on steering wheel) that this is an S-line trim packaged car so I would assume that the base version will look a good bit different both interior and exterior wise.
The only impact vent height has on comfort is if the vents are so low they are ineffective at cooling the cabin. Most people don't point the vents directly on their faces; in fact when possible HVAC systems are designed to have as low air speeds and direct airflow aimed at occupants as possible. So as long as the A-Class vents help condition the cabin effectively they are fine.
As for this new A3 I like some things about it but Audi is starting to regress in interior design and ergonomics. Thankfully this has decent steering wheel controls as I imagine those will be the infotainment's saving grace.
My issue with the last gen A3 and S3 is that they were very solid, nice cars....that were completely lacking in character. I had lots of seat time in both, and even without knocking the lack of manual transmission, neither car really brought a smile to my face. The best word to describe them would be "clinical". It's not really a knock on the car, it's just that they didn't get the blood pumping and I couldn't justify the premium. I hopped into a GTI and it *immediately* brought a smile to my face.
Cars are emotional buys. I'm a sucker. ;-)
But I like the A3 allroad idea
The interior looks like something Darth Vader would drive. Overall I like it. A car like this should have an edgy, ambitious interior and it does. Way better than the previous generation interior which I felt was just too dull to love. Throw in an E-Tron package w/a powerful PHEV package (i.e. 40+miles EV only range) and this will sell very well.
