The arrival of the Z4 (E85 in convertible form) in 2002 gave BMW the chance to sharpen up the image of its slightly underwhelming and soft Z3 predecessor.

Whilst the Z3 launched with work-a-day four cylinder power, the Z4 was initially only offered with straight six propulsion in 2.5 and 3.0-litre flavours.

Inevitably enough Alpina would get their hands on the Z4 with their version – the Roadster S – following along in 2003.

This fine example of the Alpina Roadster S in from the last year of production and drawn from the cohort of just 167 UK bound right hand drive cars made.

This example is the range topping Lux version which added xenon headlights, satellite‑navigation, 19″ wheels, heated sports seats, Bluetooth, cruise control, wind deflector, headlamp washers, and Alpina extended leather to the mix.

Only around half of the UK bound models were thought to offer the desirable Lux package.

This very rare Alpina was supplied new in February 2005 by BMW dealers Sytner of Sheffield...
