If I was you, I'd just cancel the plans the dealer sold you (if you can without penalty). Obviously, the MOPAR ESP can be had for less (Zeigler - - use the promo code "PAYINFULL".)
Dealers almost ALWAYS have coupons available. If you signed up on the Mopar Owners Center, there are always oil change coupons available (The last one I remember was 3 full synthetic oil changes for $145).
I am not sure maintenance packages are refundable if they aren't used either (ESP's are).
I'll double check on the MVP Multicare, now that you stated what you got. You're right, its by years. $500 seems about right for that.
Summary. You're obviously overpaying for the ESP and the Maintenance. I'd cancel it if you can, and buy elsewhere. You can email
