I passed on my Blue FE ID.4 reservation. I will wait for a Pro S+G later in the summer (for which I have a second reservation). So, a Blue FE ID.4 is now available at Flemington, NJ.
As a side note, the Flemington dealership has been good to deal with. Definitely better vibe than Bridgewater which I also approached. Only fee they charge at Flemington (other than state fees) is doc fee which in the $400s (I believe that is typical with other dealers in the state). They knew about the sales tax exemption in NJ.
