Okay. Everyone be nice to me. I am a 19 year old girl who needs a lot of advice with her car. I have a 2003 volkswagen jetta and it has about 112,000 miles on it. I haven't had it for 2 years yet and I am having a lot of problems. First I need a new exhaust pipe and the mechanic wants to charge me 1,100 for it. He said the part is $800. Does that price sound reasonable? Also, whenever I accelerate after driving for awhile my oil light comes on and beeps. However, my oil has been changed and it's full. Just the other day I was at a stop light and my car felt as if it was going to turn off, my grandpa said it's time for a tune up? Personally, I am nervous every time I get in the car now. I just want it to be realiable again. Has anyone had any similar problems and have advice for me. Anything will be helpful. Thanks!
