This Saris replaced my 4-bike Thule platform 2yrs ago as a superior carrier, now need to downgrade to a 2-bike identical model. Requires a 2" hitch... Looks like brand new... used a handful of times, never seen salt, and winter-stored in the basement... very quick to load/unload... allows for opening the trunk while loaded... has integrated cable locks. Retails at $1300+tax (if you can get it...).
