One further point to consider before going down the replacement starter motor route.
Bear in mind this starter was produced to BMW specs for an everyday car such as an X5, and it would have a design life of shall we assume 10 years. Now consider how many starts that say 120,000 mile BMW would have in 10 years in all weather. Now think about how many starts your almost certainly low mileage Aero might have had. Is premature starter motor failure really a likely culprit?
Just my thoughts, and a well conditioned battery, and WD40 on the starter button, is a much easier & more economical place to start. It has worked for me
