I've had a Pontiac g8 GT on the brain for the past year or so. Started to do some price checking, and realized that a similar year (2009) and mileage cts (with DI motor) is about the same price. I know the g8 is faster...but is it a better car? The caddy might be a bit pretentious for me....and the g8 is a rarer car around here. What say ye Garage forum?
