Ask Pontiac Firebird

Hi… I’d like to buy an Ami… and that’s Pontiac Firebird year 91 (up to 94). But since I know almost nothing about the car I would have asked a few people who might be better acquainted with the car. Most of the versions of the engine I’ve seen were all V6, 3.1l with 3100ccm… maybe someone can tell me which brand engines are installed in the Firebird? Then the question with taxes and insurances… How much is there about? Can someone give me approximate values? Otherwise, I would like to hear some opinions or other information about the car… so who knows please report ^_^ What do you think about with spare parts or workshops? What should you pay attention to before you get such a car? Take tips and advice gladly.
