John A, 
2006 Toyota Avalon Sedan XLS 4dr Sedan (3.5L 6cyl 5A)
A pleasure to own and drive!
 During my long life (I'm in 80s) I've had Fords, Cadillacs, Mercedes and, more recently, Toyotas -- a Highlander and now an Avalon.  Of all the cars, this one is the quietest, smoothest riding and easiest handling auto that I have ever owned. Have had no mechanical problems of any kind during it's first 15,000 miles.
