Have you tired forcing them to contact their corporate rep? From what I'm reading here, a lot of dealerships get updates from their corporate reps on when their car is.
@AspecR can you help me track the car with VIN: JHMFL5G46PX000866
Communication about it's ETA has been all over the place and I could do with some peace of mind.
Thanks in advance! You're doing god's work :D
