can you really daily drive these when necessary?

I currently own a 2002 4200 coupe and while I love it, I daily it and it breaks down from time to time. I'd like to get myself a fun and cool backup car and I have always loved the biturbo. I've owned a few e30's in the past and was hoping that one of these would be a similar experience? I may have found myself a garage queen with low mileage. I would basically need something that can do 5000 kms a year without much maintenance. Is this an unrealistic expectation for this car? I have a decent mechanic. my commute is about 15 minutes in very light traffic.
