I bought this car when it was 2 years old and had just under 60k on it. I just traded it will almost 300k on it. It looked and drove great but I really like the style of the 12's and found a very low miles one. I thought I better get one before they get much older. Other than brakes, tires and oils changes and a few other things by which I literally mean 4 or 5 things it was a great car. It never left me sitting and sInce the 2012 is basically the same powertrain I suspect I will be just as good.
If you have the 3.5 and the car overheats might as well go to a dealer the water pump is located inside the motor very costly repair. Not only did it not fix my problem I ended up having to get a new engine. Being a single mom working 2 jobs and having to spend almost 5,000.00 on a car with 97,000 miles is TERRIBLE!!!! I have always had regular maintenance on the car but once one thing went wrong it went down hill from there.
I sold my 392 Challenger and bought a used 07 MKZ AWD with roughly 90k miles. Turning 120k now and only an a/c clutch had to be replaced. I was ran off the road at an intersection by someone that blew a red light, forcing me to jump a curb. Surprisingly, no damage other than an alignment and wheel balancing. The power is very adequate (this coming from someone that had a hopped up (525hp) car. I get 25-28mpg, depending on the highway speed, typically 75mph. Pretty good mpg for an awd. Looks good, drives good, what else can you want?
