right now i'm looking at a 1997 f250 with the automatic and 4-wheel drive, i just want to know what problems i might run into with it, it has 239,000 miles, also it is selling for $9,000 is that a good price it drives great just not as much power as i expected. what should i look at on it to know if i should buy it or not. also they are getting a 2001 chevy duramax with 200,000 miles and selling for 13,000 would that be the one to go with. i really like my dads durmax. any help on this would be great i just don't want to buy a truck and then put alot of money into it diesels aren't cheap to replace. well any info that anyone can give me would be helpful.
