This F10-generation BMW Alpina B5 Biturbo is a handsomely specified example of the refined ‘super saloon’, with super low mileage for its age.

Under the bonnet sits a twin-turbocharged 4. 4-litre V8, producing just over 500bhp and driving the rear wheels via an eight-speed ZF automatic transmission with shift buttons behind the steering wheel.

This Alpina B5 Biturbo is understood to be number 21 of 320 examples produced and reportedly one of only 21 to be supplied to the UK.

The odometer shows just over 49, 800 miles, which is supported by a comprehensive service history, and has had a fresh service and new spark plugs fitted (NOVEMBER 2023) at BMW.
