im looking at an f250 extended cab long bed 2002 7.3 auto 4x4 tomorrow with 73k on it..guys selling it for 18,350.00 and its supposedly in mint condition and well maintained so far, we'll see tomorrow..used occasionally for light towing never plowing..im taking out a loan for it, but my dads buddy just told him hes getting rid of his 02 4 door regular bed...

the guys a salesman and it just had alot of highway mileage on it..never used for towing or plowing and knowing who the guy is it was probably well maintained..(he keeps his sailboat at our marina and its mint)...only thing is its got 200k on it but he wants 6k for it..

im assuming its an auto i havent spoken with him yet but this is what my dad told me so far..my intentions for the new truck are daily driver/work truck/towing the jeep to go four wheeling/plowing...i dont mind spending the money and getting the original one i wanted but am i passing up a good deal that will still work out for me without running into problems? it would be nice not to have to take out a loan..
