The 2.0 can be found much cheaper than MSRP:http://www.steepandcheap.com/kuat-nv-2-bike-rack]
That’s not the 2.0. That’s a 1.0 version that holds 2 bikes (vs 4 bikes). At $340 that’s about the going rate for the NV 1.0.
ETA: The wording in the description of the item is confusing and I can see how someone would make the same mistake.
