Im new to TDR... my first post. I have seen the light and am ready to purchase my first CTD. I am looking at a 98 2500 QC 12 valve 5spd. Its white, with aftermarket bumpers, gooseneck hitch, rhino liner, appears pretty clean, 145k miles. Guy said he'll take $15,500 for it. He seems to be knowlegdable about proper maintence and says he has changed all the fluids on a regular basis. Is this a fair price? Is the milage too high? Anything else I should look at as far as the condition of the motor. Thanks.
