There’s no getting away from it; the D5 S is a very expensive car to buy. And while its official fuel economy of 46.3mpg puts petrol sports saloons to shame, it looks less impressive next to the 53.3mpg of BMW’s 530d.
You do at least get a lot of equipment as standard, including satellite navigation, a DAB radio, cruise control and heated front seats. But then all of this is also included in a regular 5 Series.
Due to the small number of cars Alpina sells, it's hard to predict how well the D5 S will hold its value, although its rarity should help. And Alpina's three-year, 125,000-mile warranty is actually better than the 60,000 miles of cover that BMW offers.
