Buying used car in Belgrade

hello everybody



I am an university teacher and i,m planin to live for about 1 week each month in Belgrade for at leas 2 years. i will not have any sort of visa or work permit because i will stay there for 5 working days each month, total 60 days for the whole year.



Does anybody know if i can buy a car and keep it with serbian documentation? what are the required docs, procedures and respective fees?



Thank you in advance!!
