What owners say

Arnage

Overall

Owner sentiment is deeply bifurcated, split between profound appreciation for the vehicle's character and significant apprehension regarding its ownership costs and complexity. The Arnage is universally praised for its exquisite, hand-built craftsmanship, sublime highway comfort, and the visceral, powerful character of its 6.75L V8 engine, particularly in later "T" and "R" (Red Label) variants. Long-term owner reports describe it as a uniquely relaxing and authoritative grand tourer that reduces driver fatigue over long distances.

Best version to buy

Arnage T and Arnage R (Red Label): The "T" variant is highlighted for its increased power and performance. The "R" or "Red Label" is specifically and frequently recommended over the early "Green Label" BMW-engined cars.

Known issues

  • Catastrophic running costs and complex repairs: Very frequent warnings about extremely expensive parts, labor, and the necessity of specialist service.
  • Engine-specific problems (early models): Head gasket issues on early Arnage Red Label models. The BMW-sourced V8 in Green Label models is noted as less desirable and potentially less robust. Frequency: recurrent.
  • General reliability and aging systems: As a 20+ year old complex luxury car, owners report that "everything" can and will go wrong, from electrical gremlins to major mechanical failures.

Known issues

  • \nExtremely high maintenance costs and complexity: very frequent.\nChallenging parts availability: parts are described as rare, with many components cross-referencing to other manufacturers (e.g., Mercedes, BMW, GM, Lucas, Bosch) but stil…
