Hi, All, I am new to here, and probably will need a lot of help from you all as it's my first MB. Just purchased a 2011 GL450 with 45k miles on it. only 5000 miles left for factory warranty. I declined an warranty offer at the dealership as many buying guide suggests. They offer $3200 for 4 year/48000 miles. I actually would like a little longer warranty, like 7 years, the time I plan to drive this vehicle to raise my kids up. So my first question would be where is best place for me to buy my warranty. I find good reviews for carchex, warrantydirect, shall I buy from them? or I still buy through dealer. I have no idea how to start shopping. Any help is appreciated.
