Have you seen 4er in person - standing alongside F30 3er sedan, and alongside E92 3er Coupe. If not, please shut it up. Sure F32 could be called 3er Coupe (just like eg A5 could be called A4 coupe) due to same interior & other design similarities ... But compared to previous generations of 3er Coupes (which were more or less 2dr 3er sedans) this 4er is a bit different in proportions than any other 3er Coupe.
Who is telling people what should they buy? If they don't like / need some type of car, they don't buy it. It's that simple. But stop whining because such car was developed & it's on offer in your local showroom. Why even bother? If you're not interest, you're not. But obviously somebody somewhere else is. If not in US, perhaps in Germany, UK or China etc
Screaming that something is stupid because you don't like it is childish & ignorant.
Obviously BMW makes profit with every X6, 5er GT & even 3er GT sold in US - that's why they are selling them there. And it's obviously they sell more 5er GTs (although low volumes) then they ever sold 5er Tourings.
I guess you also diss CLS Shooting Break - find it utterly pointless & stupid: a retarded wagon.
Regarding jealousy ... Why mocking German carmakers? They are the most successful, most innovative & most profitable in the whole automotive industry. Just because they are expanding their product portfolios beyond your comprehension capabilities? What's wrong with having more choices? What's wrong with product that cater someone else's needs and not yours (who are not interested in such vehicle anyway). What's the problem anyway?
Really? Only because there will be a tail gate instead of conventional trunk opening? As you can see the 4er GC profile is very coupe-sedanish. It's nothing like 3er GT - which is several inches higher.
What do people expect? Vast majority even doesn't know 4er GC is coming. While those who expect to get more practical coupe will be even more thrilled when getting additional door - total of 5, not just 4.
Be sure 4er GC will be sales a hit ... just like A5 Sportback is - which isn't even sold in US. Perhaps 4er GC won't be either, who knows. Or it will be & can turn out to be a very niche vehicle - not due to its shape but mostly due to its price.
Mind in mid-sized segments practicality is more important than in full-size segments - when it comes to niche vehicles. Since they are more frequently used as family cars than their more expensive bigger siblings. That's why eg. 4er GC has 5 doors, while 6er GC only has 4 of them.
