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?
