It's amazing what some dealers will tell you, just to get you to sit down and "talk a deal". The first dealer (in Scottsdale) I talked with regarding the Challenger kept telling me about the life time warrany (we were talking about an SRT) and how they would "reduce" the Market Adjustment (but later said they wouldn't). Needless to say I purchased mine at another dealer.
There are times that the salesman just plain don't know what they are talking about, BUT at other times they do flat out lie to you...It's also amazing how the story changes from the salesman to the finance manager.
