I am purchasing a new Wrangler and I want to get the extended warranty, but I want to make sure that the warranty is not going to be voided out due to modifications I may make in the future, like suspension lift, etc... I saw somewhere in the forum where some people were saying that any modifications might void the whole warranty. Has anyone actually read the fine print? I am curious what it says. I called Jeep and they won't show me a copy of an actual policy before i buy it, which I thought was rediculous. Why should I buy before I know what I am buying?
