BMW 3 Series review

Pros

Brilliant to drive, with fantastic handling
High-quality interior with an excellent infotainment system
Great range of powerful and efficient engines

Cons

The ride can feel a bit firm, especially on M Sport models
Interior isn't quite as stylish as some rivals
It's a premium car with a premium price tag
