Romania only made half million cars last year...
Or Poland:
"The automobile industry in Poland makes up a sizeable part of the Polish economy, accounting for about 11% of Poland's industrial production. Poland is one of the largest producer of light vehicles (passenger cars) in Central and Eastern Europe. As of 2013 Poland was the 23rd largest automaker in the world."
In East Europe the top countries are:
Czech Rep., Slovakia, Hungary, Poland, Romania.
