I have a friend that is gunna sell his 4x4 blazer. Its a 2000 with 174,000 miles on it. It runs great and doesn't make any weird noises. I plan to lift it 6 inches. He told me he would sell it to me for 1900 is that a good deal? and should i be worried about the high mileage? I dont want to spend all this money in it and then it break.
