Looking to buy used truck

[flatbed94kid]

My truck had 505k. Bought more keys to be made $52. Oil change and fuel filter cost around $400. New bed mattress $150. Fuel to go to orientation cost idk 50 gallons so add that in it. Got a week on me and clutch blew out. Paid about $4600 for that out the door with sleeping in a motel.
Tires were rotten cost 3500 for the drives, then another 900 for steer which I did later. List goes and goes. Also the high pressure fuel pump cost over $4000. List goes on and on.
I would have them have a spare key, check your rubber bc I have had a blow out b4 by being cheap and only buying one or two tires instead of doing the whole set. Get a new bed. Get it ready, dont just buy it and take off. Rawze.com is your friend.
