For what its worth, I had a Plus 8 for ten years from new (2002). Owned it alongside a 911 then an Aston V8 Vantage. Now running an S1 Aero (bought last June)in place of all of the above. I can't see any downside to the Aero over the Plus 8, only significant upside as a serious driver's car. Yes the Plus 8 has the classic looks but in my view this is more than compensated for in the entirely different drive experience of the Aero which is a real pleasure, almost in 911 territory in terms of performance and handling. Running costs of the Aero are very reasonable. A few temperamental glitches largely resulting from the inadequate battery and impact on starter motor, but hopefully that seems about it. Many key components from BMW which are about as good as it gets in terms of robustness. The Aero attracts all of the attention that the Plus 8 used to, no jealousy only smiles. Can thoroughly recommend the move. As an aside seems both Plus 8s and Aeros are appreciating in value.
