I bought this baby on December 31 and between work, weather, and the heavy traffic common to urban areas, I just have not been able to get it out on an open road.
Today, I finally had the opportunity to take a nice, 120-mile round trip that mostly was on open interstate and partly on (yipee!) winding country back roads. Observations:
1. There is enough power for any sane motoring that can be done on US roads. You insane guys might be disappointed.
2. The faster you drive, the better the car feels.
3. Corners posted with warning signs saying "30 MPH!!!!" are easily taken at 70. The Pirelli's have mass grip once you get some heat in them.
4. The nav system at one point told me I was out in the middle of a corn field, but it got back on track after about a mile.
5. One major bitch: The seat cushions are way too soft. This has been a GM problem in general and a caddy problem in particular for about as long as dirt has been around. Comfortable does not equal "soft," comfortable equals "supportive." I had "car but" in only 100 miles, and this is completely unacceptable in a modern performance luxury car. It seems there are still a few leftovers from the Fleetwood days who were going to make dammed sure the STS-V had seats like a "real Cadillac." Unfortunately, they got their way.
