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?

Should I get a 2016 Honda Accord or BMW 3 Series?

I'm in the market for a new car and currently have a 2007 Toyota Corolla. I wanted to get a luxury car but they appear to be too expensive so I was looking at the 2016 Honda Accord. Is this a good car? Or should I get a pre owned mercedes or BMW? Or should I lease a luxury car? My limit is $30,000 for a car and preferably no more than 400 for monthly payments. Any other recommendations for cars?

How to keep my Honda in good shape?

Yesterday I bought a 1998 Honda Accord LX automatic for $1500 and it has 183,000 miles on it. It runs amazingly, but it needs new brake rotors which are getting replaced this weekend. I'm just worried the transmission will slip like what has happened to others. The car has a new starter, new spark plugs and spark plug wires and a new battery. I love this car and I want to keep it running good, are there any tips on how to make this car survive over 300k miles? If it helps it's a 4 cylinder vtech. How to keep my Honda in good shape - 1

2016 Honda Accord or 2016 Honda Civic?

I'm going to buy a car pretty soon and it's going to be an accord or civic.
I don't think the car will be used for a family vehicle other than for a transportation to myself and sometimes my girlfriend as well.
But then, I want a car that won't hit over 3000 rpm going just 70mph.
What should I get?

Steam coming from 2000 Honda Accord 4cyl engine bay?

When I got home after a drive around town today, I noticed a slight scent coming from my air vents (AC was NOT being used). After parking, I discovered a light but noticeably steam was coming out of the grill/hood area, checked the engine but could not find an apparent source. Looked underneath the car, and the steam appeared to be emitting from the portion of the exhaust underneath the engine, suggesting fluids leaking onto the exhaust? Fluid/coolant levels are all normal, engine temp gage is reading normally, and there are no other symptoms. Drove again and couldn't replicate the issue. Any thoughts?

Added (1). Scent didn't match up with descriptions of failed heater core smells, and there aren't really any other telltale heater core failure symptoms

How to fix fidgety car locks?

My drivers door and ignition key holes in my 1999 Honda accord always give me problems. Every single time I use them I have to wiggle the key for a few seconds for it to work. How can I fix this issue? I haven't found much information online.

Burning Excessive Oil, Bad PCV?

I recently bought an 2005 2.4 Honda Accord with 132k miles. Everything on the car is well tooken care of except burning oil. Now I did some research and said it could be a bad pcv valve. I have no leaking oil or oil in the intake and the throttle body. I put a piece of paper over the exhaust for a minute, nothing on the paper. The engine light is on saying a bad o2 sensor, replaced that and the engine light is still on. This is really confusing me and putting me in a loop. As they say there's always a reason someone sells a car. Hopefully mine doesn't have blow by or anything.
