I found an 04 V8 model, Limited, leather, loaded. It has 166K miles, and seems to be well maintained. Guy is offering it to me for $9000. By blue book it seems like a good deal, but with the rising gas prices and the 166K miles, would what you guys advise? I have to give him an answer by end of day tomorrow, or he will be trading it in on Friday. Please give your honest, no BS, opinions.
