I traded a 2005 Honda S2000 for this car - WOW! This is a car that I never believed that an US car company would build, let alone Cadillac. Its handling is up there with the top line BMW and Mercedes. Its gas mileage is 20-22 mpg. This is a very nice ride.
The Northstar motor, a 4.4L, 443hp supercharged, is an example of what US engineers can do if given the chance.
