Dear Calin 🙂
The idea behind my suggestion for Renault was that I heard they were (?) interested in opening a factory over there - or was it Peugeot...
And of course, where there's a factory, there are also mechanical parts.
My uncle, by the way, was a very famous Esatern European sportsman of German ethnic origin, who defected to Germany in 1970. As a good German, his first car was a BMW. He kept it for four years, didn't like it, and swithched to Hondas. Now he buys a new Honda Accord every seven years, and sells the old one. I know for sure that for at least one of the Accords he never had to change anything, EVER, except for oil, tires and brakes. Now, that's impressive.
As a rule, Eastern Europe is becoming the trashcan of the continent - you see on the local roads some four-wheeled things that would get you a fine in many parts of the EU. I'm not saying that an old car is not worth it, but the chances are you'll end up with a piece of junk or, at best, something stolen by gypsies and raketsi. Last time I checked, a Skoda Octavia was about $6000 US, and a similar Renault even a little cheaper. So I don't see why older models (up to four or five years) wouldn't be close to your $3000 limit. Mark my words - cars over 10 years old that still run and DON'T actually need to be taken to a mechanic every two months are extremely rare. Even German quality shouldn't be overestimated.
A local friend bought a VW Golf: over a period of several months he already had an accident, after which someone stole his VW emblem... So my guess is you also should think about the chances of that car staying intact after you buy it.
Besides which, you need a popular car model a) because this would increase your chances of finding parts and knowledgeable mechanics; b) something that would not consume a lot of gas and c) something that would withstand the crappy Romanian roads (which I know very well). I should probably add that you need something small, because of the lack of parking space.
I'm not going to ask about Dacia, but I wonder if the local factories still produce those ARO jeeps, which seemed to have established a good reputation.
I just remembered last time I was in Romania the place was awash with Daewoos, Hyundai and Kias. Are those expensive? Or how about a Lada Niva - heck, they sell those even here in Canada! Because, frankly, between an old German car and a brand-new Korean, I'd go with the Korean.
Hope this helps... and anyway, it seems I'm the only one here who was able to at least give you an answer.
