Extended warranties are a laugh riot! When we bought our '96 ES, we had the salesman say all the usual stuff ... Lexus = Toyota quality, cars in mint condition, yada yada. Then, when we start talking turkey ... out comes the extended warranty sales pitch, to handle any future problems. Sorry, but I'm buying Toyota/Lexus for a reason. I'll pay the extra as opposed to saving on a (shudders) domestic and crossing my fingers.
Point is, like all cars, wear and tear items will need to be replaced like all cars (though stuff like brakes last forever on Toyotas as opposed to GM, for ex), but it is doubtful something big and nasty is gonnna bite you on your a$$ (unless you are one of those people who are perpetually jinxed, in which case you probably should have a good life insurance policy, too :whistles:). In the end, its a gamble, do you think the repairs you will encounter (that the policy will cover -- Very Important!) will be more than the $1 000+ you are going to pay for it? Unless you quantify the "Peace of Mind" factor ...
Granted, every used car is different, but all else being equal, and painting in very wide strokes ... get an extended warranty on British cars (Land Rovers ... yikes) and forget it with Japanese ones.
my 2 cents (Cdn) -- worth a lot less with in US funds :D
