Nah, no time to go car shopping.
Plus I decided to sit tight and wait for a slightly-used CTS to come across the block. I don't want to take that huge first year hit just to say it's a new car, although I do plan on keeping whatever I buy (which is likely to be a CTS) for at least 4+ years.
I was leaning toward the G8 for a while, but at $4+ per gallon, I can't rationalize a V8 for a 50 mile roundtrip commute. I'd never keep my foot away from the gas pedal, either.

Plus, I like the styling and interior - plus nav availability - of the CTS more.
