I have been taking my cars in here for awhile. Ihave never had an issue with these people or there service. Had my spark plugs changed in my 06 Expedition, had my own spark plugs from when i was going to do it myself untill i found out what was involved. People hhow have this engine know what i am talking about. No plugs broke and all they charged me was $260 for laber and it took them 2 1/2hours to do it, cant beat that with a stick. I will always be back.
