After spending a couple of years folding my rear seats down to haul my bike to work for lunchtime/early morning rides, I finally got a Thule roof rack system and love it. The obvious caveat you'll hear is to reconsider if you park in a garage, as one day you'll forget your bike's there and "crunch"; but this isn't an issue for me as I park outdoors at home and work. Also, I had my car rear ended this w/e, although my reaction was "meh, had the car 6yrs and insurance will get this", I'd have been hopping mad if I'd wrecked a bike.
