Hello...I am looking for a used 2002-03 G500. I found one today at a small dealership that is 2002, has 109,800 miles and they are asking $25000.00. If I don't dicker with them, they will replace the windshield and buy new tires both of which are very needed. Is there any problems that I should be aware of? Is this a reasonable price? Any help would be greatly appreciated!!
