2006 Cadillac STS V6 4dr Sedan (3.6L 6cyl 5A)
The 2WD Cadillac STS has trouble going when the forecast even calls for snow. My 2% driveway grade is too much for it with just a dusting. That being said, the ride and quality is better than my previous Lexus. It's fun to drive. I had to replace the front control arm after 6,000 milies though. This is a common problem with STS and CTS according to the service manager.
