I want to buy a 2000 Ford Explorer with 122,000 miles on it and someone is willing to sell me it for 3,000. It seems in decent condition hasn't been in any accidents or wrecks or anything bad. The only thing is that it has sat for 2 years not being used...Does this really matter at all? If so how can it affect it...Because I want to take a road trip in 2 weeks in it and he says it will make it hes trustworthy but it's 2,000 miles there and back plus driving while I'm down there and I can't afford for it to break down while I'm in a strange town since I'm only 17.
