We bought the extended warrany and technical warranty only because last time we did that one week before the extended warranty expired our car came up with a huge repair bill that was covered except for the 100.00 deductable. It also included a rental car. The repair bill covered far exceeded the purchase price of the coverage. It's like Vegas...you may never need it...but we rolled the dice last time and glad we came out ahead. Really most experts will tell you not to get it. However GAP insurance is a must. If you total your Lexus this fills the gap between whaty you may owe and what your Car Insurance is willing to cover.
