This is a question that bears some answers and it's for a pretty silly reason, actually.
It seems that because BMW has made the nomenclature change and now the 3-Series coupe is called a 4-Series, folks are expecting it to have some significant changes. Meanwhile anyone who's actually owned a 3-Series or 3-Series coupe will tell you straight away that it's the same car with a sport suspension and typically larger wheels and tires.
Well, as evidenced by this Auto Express reviewer, there seems to be some disappointment towards the end of his clip. That's because he notes that folks may be let down that it's so similar to the 3'er.
Who was expecting it to be ANY different? [Shakes head]
