Craigslist ad but its through a dealer


Its the perfect all black one ive been looking for. I see nothing wrong with it, and it even has a little lift and black rims like i want which saves me money. The ad says it has 136k miles but i checked the carfax and it says 154k miles. Is that too many for 10k of asking price? It sounds like it, but its the perfect truck and i figure itll save me 1-2k in costs of new rims, tires and a slight lift.

How long is the lifespan of these trucks? It only had one owner for the 154k miles.
