We've been waiting 2 months for delivery on our new 428 convertible. Tracked it daily on its' trip from Bremerhaven. It arrived in Baltimore on 4/4 and at the dealer in Akron, Ohio on 4/10. And it is still sitting there because the dealer says all the cars that arrived that day required "software updates" that take 36 hours to complete. Has anyone ever heard of this before?? I can't find any related information.
