i was at the dealer. we only have 70k on the expedition but live in southern california. my wife drives it only to work, three days a week. we do not drive a lot on it. normal stuff.

we do not tow either. it is 2wd.

dealer tells me we were supposed to change the spark plugs at 60k because we are in an extreme driving area. isnt that more the driver than the area?

also, told me i needed to get some throttle header service done and my transmission fluid replaced. which is sealed and the owner manual says do it at 100k.

but the spark plugs are 525. another ford dealer said 680. then i read about everyones issues about spark plugs breaking during removal and you have to pay more to get them out.

should i negotiate before i go in and make sure they cover any issues? any suggestions from anyone in southern california, inland empire are?

am i being ripped off?

thanks
