Cost to extend warranty when buying new
 

Has anyone extended their warranty at the time of buying new. I'm thinking of extending my A6 warranty (had it a week now), so that it still has some warranty when I likely sell it off in four years or so. Any idea of the cost?

Usually not worth the money, and in many cases only covers the initial buyer. On an Audi it will run over $ 1000. Ask your dealer, they will be more than happy to to give you a price and sell you the warranty.
