I own an 06' FX45 I bought new.
Prior to that I have had: 3 80's Z28 camaros, 2 crappy station waggons, a 63 GMC step side pickup with a 396 BB, a new 94 mustang GT, a new 96 F-150, a new 99 Yukon Denali, a leased Viper for a few months, a new Qx4 and my wife has a 350z. I've also driven many, many different cars, trucks, suv's, exotics, ect. because of my work.
That being said, the FX45 is hands down the nicest vehicle ive ever owned and one of the nicest vehicles ive ever driven.
Hope that helps.
