Regarding your point number 2, your post number 20 in here contradicts you completely: the event you identify in post 20 went as follows, as I recall -- BMW did a recall and provided replacement bikes to those effected by the recall in the UK for the time that the bikes were off the road; the new water cooled RT were replaced with loan bikes, usually water cooled GSs, and the local dealers had to step up to the plate and deal with this, often providing their own demo bikes.
They also collected the machines from the owners for the recall work because "they could not be ridden". As an anecdote, it is said that one UK registered bike was recovered from mainland Europe and the owner, on vacation at the time, was provided with a replacement bike to continue the holiday.
In the USA, because those guys are much more prone to go to law very quickly, they did something along the same lines and made compensation payments to the owners - I forget the details but it was in the order of a few 1000 US$ per customer.
All this was done for a safety-related recall; contrary to your point 2 above.
I don't know of another manufacturer that would provide anything like this level of service; maybe you do?

"Which Bike"
"What we need to be aware of when buying a new bike today"
Just how unrelated can a thread become to both the forum and its own title; it needs to go into the BMW thread so that all potential purchasers can be aware (of something or other).
