BMW 3 Series – Diesel

The 3 Series is a popular choice with company car drivers, particularly in diesel form. According to our fuel calculator that’s a good thing, at least if you cover a lot of miles. The 320d costs £2205 more than the equivalent 320i, but if you’re a high mileage driver then the difference will probably be paid for within three years – plus you get cheaper tax disks and a lower BIK rate.

That said, it’ll take a long time to pay that difference off in savings if you’re a low mile driver and a low BIK rate only helps company car drivers, not private buyers.
