BMW 4 Series review

Pros

Stunning, athletic styling that really stands out
Fantastic to drive, with an engaging and sporty feel
High-quality interior packed with excellent technology

Cons

The ride can be quite firm, especially on M Sport models
Practicality is compromised compared to a 3 Series saloon
Diesel engines can lack a little refinement compared to the petrols
