Hey I have been real nervous about my truck after the injector froze open and blew the Catalytic converter. I investigated the esp warranty thru ford online and found a 6 year 75k miles basic esp for $970 with a $50 deductable. they gave me a code for an additional $185 off that price. Is $810 a good price for 6 year 75k on a 2005 F150 with 21k miles?
