Auto Repair

I took my car into a mechanic. had them look at a check engine light. They hook it up to a computer and it tells them that I need new spark plugs and iginiation wires. the next day I get my car back, I have a low oil pressure warning. I take it to Jiffy Lube to get the oil changed, they inform me I'm a quart to two quarts overfull on oil, and change the fluids. Car is now making a horrible noise so I take it back to the mechanic and then am told that the oil pump failed a mere 24 hours after I got it back. This ended up destroying my engine. Now I didn't put any oil in this car, ever. They claim to not have put oil in. So they offer to sell me a new engine, and while they are trying to repair my car, new things keep becomming problems that I never had issues with, like my radiatior suddenly has a hole in the middle of it. What options do I legally have. I've not signed any estimates, and I'm fearing that the end bill will be more than the car is worth. - Is this your question? Add additional information
