I've always bought the extended warranty on all vehicles I've owned and for one reason or another I've always seem to come out ahead on them as well. Even on My civic I've had many years ago, it saved me about $3500 in the longrun. Now I have my '90 LS and I bought one as well. It has 113k on it and I don't expect anything to go wrong with it anytime soon, BUT if it does, I also know it won't be cheap to fix. Besides the warranty I bought covers just about everything, even down to the seatmotors and A/C. So if my A/C compressor decides to give up live, it'll cost me $50 and it just paid for the warranty.
Kind of like carinsurance. I've never had an accident, ever, yet I pay month after month, just in case I do oneday.
