Actually since I purchased the car as a CPO, the price difference was only a couple thousands, so that was not the main reason for me.
I researched the car for about 3 month prior to purchase and was just really taken off but the failures of the turbo engine. Yes I know most if not all issues were solved, but it did leave a taste of unreliability in my mouth and the 128 was deemed very reliable at several published magazines. Since it is my daily driver I was also very happy with the gas milage. I only wish I would have gotten a manual, even though the automatic in 100% manual mode works just fine. When buying a CPO, you just don't have that many choices, and new did not make any financial sense to me.
Would I do it again, probably yes unless the reliability of next generation engines improves a lot and gas mileage would not be an issue anymore since I started to work full time from home.
