Ouch..neither would I. lol..I drove to Munich for BMW welt and spent the day ther 5 hours away I understand. Had a blast comming back though, played with e30 M and his crew of 3.0 supra/300zx/350z **sorry off topic**
Zurich, Switzzz lemme google.
Back, your 4 hours and 20 minutes from me...and thats 4 hrs 52 from the ring to Zurich. I'm sure you can make it 4 hrs and 15 flat. Not to harsh of a drive, but I would definitely suggest sleeping before driving home of course. If your not to weird or needed to use a lift I have the extra space/facilities at my house.
