I purchased a $2400 extended warranty from Enterprise Car Sales. Once I saw the balance on my loan was so high (after putting $5,000 down on a $7999 car), I called about the balance, learned it was in part because of the $2400 warranty, and then cancelled the extended warranty policy. The Enterprise Sales person told me he faxed it in on 8/4. However, the change still hasn't appeared on the Chase Bank (lender) website, and they tell me it takes 6 to 8 weeks. In addition, the Enterprise Sales manager blocked my email. Nice.
In the meantime, I found another warranty from AA Auto for $1698 with $100 deductible, which will work fine.
I think Enterprise Car Salespeople are very slick, particularly in what they don't tell you.
Do not recommend Enterprise Car Sales.
