BMW Alpina B3 S Bi-Turbo Convertible | 2011 | 400bhp | B3 BTV

A rare opportunity to own a beautifully presented BMW Alpina B3 S Bi-Turbo Convertible, based on the E93 3 Series. First registered on 22 October 2011, this striking example is finished in Crimson Red and wears the private registration B3 BTV.

Its 3.0-litre straight-six twin-turbo engine produces 400bhp, with a quoted 0–60mph time of 4.7 seconds and a top speed of 186mph. It delivers serious performance with the pleasure of open-top motoring.

The car has a service book and an extensive collection of receipts, reports and supporting paperwork. Recorded services include:

2012 — 4,834 miles, 2014 — 18,669 miles, 2016 — 35,640 miles, 2018 — 46,765 miles, 2020 — 52,688 miles, 2023 — 58,462 miles, 2024 — 63,248 miles, 2025 — 64,256 miles, 2026 — 68,852 miles

The history shows a car that has been carefully maintained, both mechanically and cosmetically. In 2025, nearly £4,000 was spent addressing a misfire, including spark plugs, coils and fuel injectors. The engine was inspected by borescope, with the report finding the bores in good condition. The brake fluid was also changed.

At its 2026 service, completed at 68,852 miles, the car received oil and filter, ignition coils and two turbo solenoids, with around £1,000 spent. Other recorded work includes front shock absorbers and bump stops in 2022, a Pipercross air filter, and a cam-cover gasket to remedy an oil leak in 2021. The car also received a service and specialist ceramic coating in 2022.

The last recorded MOT was on 16 March 2026 at 67,523 miles. Since then, the car completed a European road trip through France, Italy, Germany and Belgium, covering 2500+ miles and showing how well suited it is to touring.

The car sits on 19-inch genuine ALPINA multi-spoke wheels with Michelin tyres all round. It also features an ALPINA rear diffuser, boot spoiler and quad exhaust system. Inside, there are distinctive ALPINA seat badges and door-card detailing, a custom black and red leather ALPINA steering wheel, and a piano-finish dashboard with ALPINA detailing. Further features include heated seats, an ALPINA rear wind deflector and cupholders for both driver and passenger.

Paperwork supplied with the car states that 25 examples were produced for the UK; buyers are welcome to inspect the supporting documentation.

A highly distinctive RARE ALPINA with exceptional performance, comprehensive history and a superb combination of colour and specification. It is a car that has clearly been cherished and enjoyed.
