Well, I'd be in the 3% that wouldn't order aircon
Think back to 2005 though before the JCW kit became factory fit... Your Cooper S cost you £16k, aircon was £600, brakes were £500 plus dealer fitting, add £1k on for alloys, add another £300 for stereo, then £3k plus fitting for your JCW kit and you're well over £22k, so considering prices are supposed to have increased, this represents good value
