The car has a slight idle problem.
The car rides as smooth as glass.
The cabin is superb and really caters to the driver's needs.
Regarding the idle problem. According to My Cadillac dealer this is a very common problem with these North Star high performance engines. It is very expensive, about $1000 CD to replace plugs and wires, but this seems to fix the problem 9 out 10 times. I had a local GM dealer try numerous fixes including resealing the intake manifold and PCV Valve, but none of these fixes worked. They were guessing at the problem and finally refused to work on the car. They advised to take the car to a Cadillac dealer well versed with the North star engine, and that would be my recommendation to you.
