I'd call it fully priced, at least, for a very nice BN1, and the custom colors in the interior narrow the potential customer population. The BN2 is simply more highly pursued and thus brings more $$$.
My main objection is of course the fact that they are masquerading it as a 100M or Le Mans or possessing the non-existent "Le Mans Appearance Package" (Le Mans is two words and I can't bring myself to write it as one). Sellers just cannot resist the temptation to try to suggest that their non-M is an M or close to one or should be worth as much as one, or just as good as one, etc., etc., etc. For crying out loud, they've even attached a little letter "M" to the 100 flash on the grille as found only on some 100M cars (and attached it in an incorrect position, but what do you expect?).
There's no shame in a nice, plain, standard BN1 (although this one has lost its 3-speed gearbox - PITY!), so it is a shame they they're trying to make it something that it is not. Still crying out loud: The standard BN1 is getting to be more rare than one with a Le Mans Kit! (Or should I say, the "Le Mans Appearance Package"?)
