The MB Market Insights
Pricing in at more than $8k in the 90's for an M103 power increase is serious business and considering you can't walk into a BRABUS or any of their authorized dealers to grab one makes this a rare red head. Those hunting for one might get lucky on the forums or an international site occaisionally but this real deal BRABUS part is only available here and your M103 could be the first one it's seen.
