Im looking at getting the extended warranty on my 2011 GU7. Is it a fixed price to get the extended warranty, or is it worth shopping around different dealers in my area to get the best price? Also, is it worth the money and are Nissan likely come to the party if something goes wrong? Lastly, what are the likely things a 2011 CRD is likely to have go wrong during the warranty period and do they outweigh the cost of extended warranty? Thanks in advance, Ralph.
