The country is not as important as the previous owner. This one's interior seems a bit filthy for such a low mileage car, so you better have it inspected before you buy it as you can't just rely on the low mileage and expect regular maintenance from the previous owner. Italian cars tend to have less rust, but for the three years you plan to own it it won't fall apart regardless where you buy it from. As for selling it for 7-9k euros in Bulgaria - fahgettaboutit
Everyone will tell you how they start at 1.5k in the ad sites (even less in 3 years). Good luck.
