Your location is very relevant to your question. For example, if you live in Florida, you have to buy the warranty in that state. It's the law.
I beg to differ. Florida dealers (Ford, Chevy, Honda, .....) all say they cannot discount extended warrantees, because the Florida insurance commission says so. But that is total BS, an excuse to keep prices inflated at MSRP. And because of this, many out of state dealers will not sell extended warrantees to Florida residents.
BUT - if you are a Floridian, and you make enough (out of state) phone calls, you WILL find a dealer who will sell to you at a substantial discount.
I am a Floridian, and have bought OEM extended warranties from out of state dealers for 1/2 of what Florida dealers wanted, for Honda motorcycles, Mercury, Ford, and Honda cars. And the warranties I bought were all honored by Florida dealers.
So all my fellow Floridians - do not be suckered into paying full price for extended warrantees from Florida dealers.
When my factory (5 year) warranty is nearly up on my G80, I will call every USA Genesis dealer until I find one that will sell me the extended warranty at a steeply discounted price. And if anyone has already been able to buy an OEM Genesis warranty on the cheap, please post the dealers contact info.
