These are probably more-so for On the Lot inventory. That would be my guess.
The original post gave the impression that you can really order whatever you want, but these are line-specific options.
The question becomes then, what does a standard 3 series not denoted within one of the "lines" look like regarding bumpers, accents, etc.
The shame is I love the contrast of the SPORT, but the interior looks cheap because of that red line going down it. Looks like we'll have more waiting to see.
