At a previous job I occasionally used my little plane to fly into the hub when I had ground school/training.
If I drove, it typically took me about an hour to get to the training center, but instead if I drove out to the local G/A airport, pulled the plane out of the hangar, preflighted, taxied out and flew to the hub, secured the plane at the FBO and then bummed a ride from them over to the training center it only took 1:10. ; ) But it was fun when the weather was nice. That's about the extent to which I would use a personal plane for work.
