People flock like no other to the E-Class AMG (various flavors, but in general), and that goes well in head-to-head competition with the M5. I certainly see more E-Class AMG's around, but that's simply because I think it seems more luxurious while maintaining its bad-ass attitude on the exterior. But certainly BMW is making some good money off that M5, right? The M3 is tearing apart the C-Class AMG as far as I can see - the M3 has long been the gold standard of its class and there's good reason for that. Now let's take a look at the high-performance luxury flagship sedan - the 7 Series vs. S- Class. Both do well in terms of sales, but when it comes to downright luxury, few people want the BMW. But there's not even a choice for those who want a kick out of their behemoth sedan - there is no M7!! There is only the S-Class AMGs, which are exorbitantly priced and are selling extremely well. Why can't BMW plop a nice turbocharged engine in their standard 7 and run with it? Maybe just use the same one from the M6? I feel like there's money on the table. And yeah, the Alpina B7 isn't enough. Make it production and not impossibly rare!
