I think that checking with customers on a waiting list in situations like this can be difficult, specially when the list gets close to a 1k like in some major metro areas in the US. Of course with the right software it can be done, but most dealers in the US seem to be operating out of folders
On the other hand if I'd been waiting for a year and a pre-specced car arrived that matched my order and it was sold to a walk in at MSRP, then I'd go nuts.
It sucks waiting, doesn't it.
