I see what you mean about the Hyundai looking tail lights in the rear end, but in person, there is no mistaking the two, the Quattroporte has a really great presence. I've only seen one, but it's made quite an impression! Take a look at their website, they are customizeable in nearly every way...you pick the interior colors for the seats, headliner, steering wheel, carpet, seat piping, trim, and steering wheel wood finish, not to mention all of the packages/options available! Outside, you pick the paint color, caliper color, and rims.
Take a look at the Quattroporte website to see all of the pictures and options. I think its luxury is on par with the competition, but the Quattroporte has one over the competiton, everyone and their brother isn't driving them! lol B)

Go drive the MASERATI and you will experience a new level of luxury, Speed and control. Enough said. This topic is a dead duck in my opinion. If you can't make up your own mind on a auto what makes you think someone else will make it for you? <_<
