problems with my 03 mazdaspeed
 

well i bought this car in late april of this year and it didnt have any problems then but since then it has had the check engine light on continously and i brought it into the dealer and they said it was the thermostat and they replaced it so then about 5 days later the light started to come on again and i have been driving it around and i notice that the engine hesitates at about 3500 rpm so i got it looked and the first place i brought it to did a smoke test and then said it was this vacumn tubing and the part alone was about 700 dollars so i was like is this covered by my warrenty(bought an aftermarket one for 3 year or 36000 miles) note: this car has 730000 miles and is not covered by the manufacturer warrenty well anyways back onto the results of my warrenty turns out it is not covered by my warrenty so my mom calls up the dealer(im still 17 :( ) and they say its not their fault because it was 31 days and the dealer warrenty is only 30 so they tell us about this place that is suppose to do that vacumn tubing repairs for about 1/2 the cost of the other place we went to so i brought it to them and they said that the tubing would still cost the same but they checked it and said it was the rear oxygen sensor and that it needs replacing(also not covered by warrenty) so i got that replace about 320 dollars in all and the check engine light comes on later that day so i bring it back to these people and they check it and it still says the same thing that it is a lean code and the o2 sensor should of fixed it but didnt and they dont know what to do. So, they give me this number to a performance place which i havent called yet because i think their gonna say that i need those expensive ass tubes replaced also, my struts r extremely squeeky and the guy before me pulled out my rear speakers that are right behind the rear passengers head and he also took out the stock amp for my sub thing.

So my question for u is wtf should i do go find a drunk driver to hit my front end and get it all covered by insurence or spend a shit load on repairs?
