Is it possible to safely fit a pair of skis inside a 1973 Super Beetle?

Not unless you take out one of the little windows up front.

If not, you can borrow the Toyota. Some douche-bag relieved us of the passenger window and stereo last night.

Yes, but you can't have any passengers in the front seat.

Just put the skis in the passenger side with the ends on the floor.  The other ends go between the seat and rear side window.  To prevent scraping, toss a jacket over it.
