this is getting uglier by the day..i swear i am going to either buy a honda accord or some high mileage yoda..i am thru with american car companies..i feel for you guys who paid in full the costs of your chally...but how in the heck can a build date be top secret?..that just floors myself and is another indication that the big 3 do not care about customers and have refused to learn the lesson of the past 30 years...all of em are still stuck in the 60's..
