I have been in the " extended warranty" business for now 42 years . My first advice is to drive them and buy what you like the most . Second , if all things are fairly equal , check and see if one of them has a really good rebate or finance special going on when you are ready to pull the trigger. All that being said , our company is losing its' ass on both GM and Ford transmissions over the past two years in both trucks and suv's !!
