2005 BMW Alpina Roadster S

KEY FACTS A rare and exciting modern classic roadster, this BMW Alpina Z4 Roadster S combines open-top motoring with enhanced performance from the renowned German tuner. Under the bonnet is a 3.3-litre naturally aspirated straight-six engine, driving the rear wheels via a six-speed manual transmission. This UK-market example was first registered in July 2005, and has been with the seller for over 16 years. This Alpina Z4 Roadster S is one of only 167 UK-supplied examples. The odometer shows just 33,755 miles from new. EQUIPMENT AND FEATURES The engine found in the Alpina Roadster is a hand-built 3.3-litre straight six, related to the S52 unit found in the North American specification E36 M3. Alpina made thousands of revisions to BMW’s Z4, including Alpina-tuned suspension and drivetrain – with a shorter rear axle ratio – plus signature upgrades such as high-strength Mahle pistons and an Alpina-specific cylinder head and crankshaft. This example is finished in a timeless shade of silver over a red and black leather-trimmed interior. It rides on 19-inch Alpina quad five-spoke alloy wheels, framing red brake callipers and fitted with Toyo Proxes Sport 2 tyres. Equipment includes a BMW Business CD stereo, automatic air conditioning, Dynamic Traction Control, an electrically operated convertible roof, and electrically adjustable heated seats with three-position driver memory. A factory hardtop is also included with a purpose-made stand and cover. Accompanied by the service book, a leather Alpina wallet, original Alpina brochures, all original and unused tools in the boot, the V5C, and two keys.
