Re: Air Suspension, Saddle, Bluetooth....Reservations...
The QL is not generally problematic, or if it is, we don't know that yet. There's been a couple people with an issue, but both have had it easily remedied. Mine and that of other people have worked perfectly. Personally, I'm not worried about it. My only concern might be a leak in the system, but it uses pretty standard nitrogen, and any competent service department should be able to get it fixed rather quickly if something does go wrong.
Saddle is hard to get thanks to demand for the Summit.
For Bluetooth, it seems limited to a couple things- the iPhone 4 and the music streaming. Mine (730N) works perfectly for the phone, and the voice command is far better than I'd expected it would be; it's way advanced over the HandsFreeLink system in my wife's 2006 Acura TL.
