Just bought an old car, costing me a lot of money, what are my rights?

I bought a 2004 Honda civic from my mechanic 4 months ago (190,000 miles) he had gone through and fixed everything and was going to charge me accordingly.
When all was said and done, it was about $4,300.
A couple weeks later, my check engine came on, no heat and the car was stalling… Brought it in and he fixed it for a couple hundred
A month after that the engine starts to rattle like mad and the car won't move… Brought it in, he said the transmission is bad, fixed it for $1,200
2 months later (currently) no heat, smoke pouring out from under my hood, I pull over and anti freeze has exploded all over everything…
This time I take it to my boyfriends mechanic, he says all 4 of my ignition coils are bad and my car is burning anti freeze. He s replacing the coils for me… Now what can/should I do about this? Do I have any rights to go after my mechanic?

None. You bought a car with 190K miles on it. It's old. Things are going to break. It's not your mechanic's fault that things break. You should take a good hard look in the mirror and question the judgement of that person.

"what are my rights?"

You have the right to continue fixing it or buy a different car.

NO… He got you once,… Then you came back for more

I'm with Stpaulguy. So you bought a car, and had enough money for, what, by my tally $5700 in repairs. Had you have gone and found a newer car with fewer miles, $5700 would have made a REAL nice down payment on, say, a $15,000 car. You would have had 1/3 down, so that would have qualified you for a real cheap interest rate, you could have got into a 2012 Honda Civic for less than $15,000, would have probably had 20,000 miles or so and you'd be better off in every way than you are now. Lets say you dump another $5000 in repair. How much do you suppose a 2004 Civic will be worth if you hang on to it for 3 or 4 years? It's time to do a little more research and learn how to properly choose a car for yourself rather than looking for someone to come along and pay for your mistakes. If you want to maintain a sense of entitlement, then change it to being entitled to learn, which you ARE, rather than being entitled to forcing someone else to make up for your poor decision making, which you aren't.
And stop voting democrat. Care to guess how I know you vote democrat?

Problem is, you bought a Honda, and all Hondas are JUNK
