The correct dealer cost on the "E" Group is $951 (originally $1011). The $2000 MSRP has never changed.
Did they end up soaking you for $1780?
The dealer eventually came back and claimed it was some invoicing issue between them and Chrysler that they needed to correct with Chrysler. I was never made privy to what exactly went wrong, but I never had to pay any more than what we originally had agreed upon.
