I just got the 06 STS 1SG AWD and I absolutely love it. I agree that it is a much more refined car with many more luxury options, not too mention the Northstar. You definately need to drive it, you will be very impressed.jimbohenson said:I have had my 05 CTS-V for about 9 months and just as many trips to service. I am trying to convince cadillac to "upgrade" me to a STS V8 1sg all wheel drive. Any suggestions ro arguments either way.
