The ONLY reason Ford addressed the Firestone issue, the cruise control issue, etc was due to safety concerns. Ford has shown that they are unwilling to offer not much if any customer support. In return, I wont be displaying any more support as a consumer to Ford unless they can prove otherwise.

As far as leaving in your spark plugs for 168k miles, or even 100k miles for that matter, Id be willing to say that you will most likely have major problems removing the plugs, and even venture to say that probably most of the plugs will be siezed at that point. Im right at 25k miles and Im dreading replacing them. Im having detonation issues and think I will take it to the dealer first, of course they will charge an arm and a leg to replace these things. Let me grab the KW now...
