Hi Dave,
the mileage on the Aero is probably best described as the lower mileage the better, same for the amount of owners the vehicle has had.
I waited and bought a fine low mileage, low owners example privately for about 10k less than a london dealer would charge.
The drivetrain is very good and I would not expect to see any problems in that area with a mileage of around 30k, however I do agree that 30k is quite high,
I would wait and see if something with lower mileage turns up if it were me buying.
all the best,
Ian.
