Hello To All: I am new to this forum and am thinking about buying a used 2004/2005 GX470 from Lexus of Merrillville, IN. They have a lifetime powertrain warranty on certain vehicles under 100K miles that seems very legit, but I do not know anything about them, etc. Cannot find any complaints on the Web, so just would like to know if any of you have heard anything good/bad about this dealership's warranty. Have not made a deal yet...kind of nervous!! Need help if you can! Thanks!
