Find Jeep Dealers in Jacksonville, Florida

Hi gang, I don't know if this is the right place to ask this question, but my Cousin, who lives in Jacksonville FL, purchased an used 2001 Jeep Grand Cherokee (V8) with 58,000 miles on it last Saturday from Arlington Toyota in Jacksonville FL. His term is for 72months at 10.72% apr His purchasing price (which I thought was high) was $18,999. But the biggest problem that I had was with the extended warranty cost that I found in the contract. After faxing me over his purchasing invoice, I noticed that they charge him $2,545!!!! for an extended warranty. I totally believed that they took him for a ride. Since his English is not that good, I am convince that the finance manager took complete advantage of him. No only I think that $2,545 is far too excessive for an extended warranty, but I think that it is definetively worthless, do you guys agree??? I am planning to write a letter to Toyota and to the dealership itself to complain about the deceptive tactics of the manager, but I wanted to see if you guys know if you can get a refund after buying an extended Warranty, or have that charge taken off the total price financed. Any ideas or experiences will be greatly appreciated. Thanks
