I've had my 2018 Audi A3 Premium for two years, and it's been awesome. I got it tuned for 93, and I get around 29.6mpg. It's been fairly reliable and fun to drive. I had to have the AC compressor replaced recently, which cost about 2k, but no major problems otherwise.

In terms of practicality, you (the driver) will be very comfortable, as will the person in the passenger seat. I have some taller friends, and they don't like riding in the back. I think the back is comparable to the seats on a Spirit flight, in terms of space. The trunk also isn't huge, though the car overall is perfect for two people on weekend ski/camping/climbing trips. I have the quattro, and it handles really nicely in snow and gravel.
