I bought an extended warranty just so they would lower my financing from 4% to 3%. I canceled it the next day and got a full refund and kept the lower percentage. I could have got 0% financing but I took like $1500 in dealer incentives instead. Paid my car off 18 months later and it all worked out.
But I digress, the original dealer charge me like $2800 for the warranty and shopping around yielded an out of state dealer that sold them for like $1200. Shopping around is definitely the best bet
