Leaving the country in about a year and a half. Need to turn in my lease this month.

So the lease is up on my 2016 Jetta Sport and I'll be turning it in this month. Normally I would lease another car, but since I'm leaving the country in a year and a half I don't think it would workout as they seem to do only 3 years. I don't think buying new makes sense either. Currently I'm looking at a 2006 BMW 325i that's going for 5900. Would just buying something like this for the time being be the best thing to do? Are there other options I'm not thinking of? My credit is 770..
