Thanks all for the feedback and comments, very useful.
Lightsphere, don't hesitate getting an early Aero, despite some of my (largely unfounded) reservations/concerns, they are great cars.
Philippo, thanks for the suggestion on how to jack the car up. I will try and replicate what you have done as knowing that I can get the wheels off, if required, will give me a lot more peace of mind.
Aero S1's seem really thin on the ground now, there is only one for sale (Techniques) that I am aware of!
