I'm purchasing a 2008 Kia Sedona-Kia certified with a 5 year 48,000 mile warranty. They want me to purchase an additional 52,000 miles and five years bumper to bumper warranty for 10 years total and the mileage would expire at 152,000 miles for $2100. They have thrown in 5 years of clicker coverage for free. The warranty is fully transferable. I normally don't buy these things but I also know how expensive cars can get after 100,000 miles. The question is how much of that will be covered and how much will be wear and tear. My real question is it worth the price tag or am I being taken for an expensive ride for the sake of security?.
