The STS-V is a nice step for Cadillac into the performance division of cars but it comes up short in several key areas. The first thing that you'll notice when you get into the car and start driving is the poor handling. The car's handling is incredibly sloppy. The Cadillac reps said thats because it wasn't designed to handle, just go straight. Well the E55 is faster and the M5 handles better so what does the Cadillac do? The interior is subpar, with the rear seat using primative HVAC controls. The front seats are not sport seats and have no side support. The interior itself is ok, but nothing fantastic.
The car looks great, has great rims on it, and the mesh grill is a nice touch. It gets an overall A+ on the styling front.
Improve the handling, get rid of the hesitation when you floor it, improve the interior, make it better than the Mercedes-Benz E55 or BMW M5, which are in some category, to make me want to buy one.
