 I've been in a Q45 since 1991 and this is by far the 
best one yet. I don't agree with the "soft 
suspension" review from Edmunds. It takes curves 
quite nicely without tossing the passengers around. 
 The engine and transmission are works of art. The 
VDC would not allow me to slip or fishtail in the 
snow, and I did try. 
 The dashboard controls are quite intuitive, I only 
referred to the manuals briefly. You can voice 
command anything you don't feel like reaching for.
 The Nav System is unbelievably accurate and quite 
easy to follow with expanded intersection diagrams 
as you approach a turn.
