[ I don't think you're missing much. The bag is actually canvas and not leather as I initially thought. It contains a wheelbrace and a jack - not much use in a car without a spare wheel
My guess is that it may have been added along the way and never came with the car in the first place???
My new (ish) Aero +8 didn't come with a jack. Would you let me know who makes that jack and what the model is? I might try and buy one. Thanks....
