Looking at getting a 4 year/60,000 ext warranty from carchex for the 06 2500 I just bought. $2,200 and covers quite a bit. Truck has 65,000 miles on it now. I am pretty mechanically minded and have my bro-in-law on salary who used to be a mechanic. He thought it was still a good deal for $500-600 year esp if something major went out. Just looking for other inputs from people that have used it or what thoughts are on why didn't use it. Thanks in advance!
