I purchased my 4.6 w/tech 11/15/08. Since that day I probably haven't missed one day that I didn't drive it except if away. Today Ihave 30,000. Yesterday I drove the Equus signature andfound it to be a great vehicle. Immediate difference Inoted were absolute quietness. The massage on my back was pleasant and I am sure I would love it when the sciatica happens. It appeared "bigger" in and out. Suspension was notably softer. On the road, she responded as wellas my car, cornered as well, Audio the same. All maintenance save tires are "free" for 50K miles. It EXCEPT I can't put my hands around the $20,000 difference. $10,000 ok. Mydealer has had 4 so far and all went quickly at sticker. No bump up! But none of the purchasers were previous Genesis owners. That is the big question. Is the Equus $20,000 better then the Genesis 4.6? I don't think so. I really would like to know of the Equus purchasers were trading in their Genesis. I guess I will wait for a demo next year. Maybe I am wrong. I could write a check for the car but just don't see the value difference.
