IF you didn't have a wedding ceremony, are you really married? You at least had to stand in front of a judge, pledge yourselves to each other and sign the marriage certificate. IF you didn't do that - you are NOT married.
Sounds like you need to get a job - any job that will allow you to start earning and banking some money of your own. You are not wrong about wanting a car - it represents personal freedom these days and I wonder if not getting you one is a way to "keep you" close.
IF this guy is good to you - you get to come and go as you please (albeit on public transportation or foot), doesn't hit you, you get to purchase a few things here and there that you like, etc then it may just mean he is not well off.
BUT if you are just left to cook and clean, never get to go anywhere without him, he hits you or keeps you from doing things you want to do, then you are being abused and need to seek help asap!!
