1.5 years of ownership is a decent amount of time, IMO - that wouldn't worry me. I've never owned a car for that long and sold on without issues. The only shed I bought that did have issues, went on ebay with a full list of the known problems for £200 haha.
If it's a long way to go, I'd be asking a lot of questions before making the trek.
What's the car? Is it really that hard to get one in similar spec for similar money nearer to you?
feb 2010 to august 2012 = 2.5years.

although agree that's a fair amount of time.
