I think the dealers use very rubbery terms in describing where your order/car is (may be they just don't know either), if the dealer can quote you a six digit KIA order number you at least know it's in KIAs system, the order you signed was just with the dealer remember.
Originally ordered with dealer early December, ETA end of February, updated verbally to March/April.
I have see late Dec/early Jan ordered cars already delivered in Feb, so who knows.
I have the KIA order number and my latest update says it's 'In Build' and I have a
VIN now. So it's got to be getting closer now. I hope.
