Hi,
I think it depends on personal perception. If you are someone who had been very used to a new age car, you may find it a bit uncomfortable and impractical. On the other hand, if you are not, you may find it more acceptable in terms of comfort, handling and etc etc...
Also, daily basis can differ alot depending on your time spent on driving. Is it just to commute from home and office? Or do you drive to many destination everyday? Far or near ? All are factors...
For me, the e30, if well maintained, can be everyday car provided you can accept the 20 yr old technology. For me, it is fine as my usage is quite minimal everyday. It has power steering, power window, air cond, for me thats the minimal requirement for everyday usage. It was my everyday car for the past 6 years and still is but lesser now since i alternate it with another car. And the last 6 years, it has never fail me. I do very little mileage everyday though.
The e30 is a very special car. Driving pleasure is almost second to none. Well, personal of course but for me, e36 or e46 cannot give me the same feeling of 'attach' and 'confident'....for some reasons...it is weird

e90 is just too big for a 3 series, imho....i never understand why cars keep getting fatter...? Though i do agree that e30 is a little too small for 4 adults....but i cannot imagine what would a 7 series be like in another 3 generations....

lets see if anybody can remember this and bring up this post after 3 generations in future

hope everybody gets to see it.
My humbly 2c....
