We had our 10 for two and half years of trouble free service . It was a good car. We have had our 13 for about 10 months now. It is a much better car. More refined, and anyone that tells you that the 3.6 doesn't make a big difference is feeding you a load of bull. While I never felt the 3.0 was vastly underpowered, I didn't like the loud noise it made when you had to really get on it, and it seemed like it was straining. No problems like that with the 3.6. It is smooth, quiet, and gets as good or better mileage than the 3.0 Take most of the people's advice and go for a 12 or 14 if possible. I know last year at this time, my dealer had a lot of 12 demos for sale at great prices.
