At best, I've broken even over the years on extended warranties with a couple of my cars. The rest have seen me taking a bath in the money I've forked over at closing.
I continue to purchase imports when I'm in the market, simply because I've had the greatest luck with Toyotas, Nissans, and Subarus. Considering I've been driving for 36 years, that's a pretty good track record.
I will say, however, that the new Ford Bronco looks kinda interesting.
