That's such a good idea

 

I'm new, as I'm looking for a good used F150 and the info here is excellent from what I can tell.
I live in remote NM and internet is how I find most things,just takes a long time to sort out BS.
Like is CarFax good or ?
Is 4.6 v8 reliable?
And now pointers on buying.
Any advice for retired guy looking for deal on a used truck. Seems I have found many ext cabs,fx,clean,1-2 owners, cheap. Trying to figure out the catch...I think it's folks want to tow more or think they need 4 dr or ?
