2005 F150 Ford Lariatte Quad Cab Black on Black New Crate Motor 50,000 miles

I replaced the motor right about 50,000 miles ago. I think I have paperwork from Ford where we purchased the BRAND NEW CRATE MOTOR right out of the box. This cost was right at $ 8,000 to buy new and install.... I planned on keeping the truck however after changing jobs the company I now work for will not pay my car allowance for any vehicles over five years old so it just made sense to buy a new car.....when this truck is clean and waxed itlooks very nice ...its very dependable...cash buy is $ 8,500......however Imight be willing to finance with down payment... the cost would be q little more...
