I have a 2005 Chevy Cobalt base model coupe with 105,000 miles on it, I had the oil changed and shortly after the car started acting up. I took it to Auto Zone and it threw 3 codes. I took the codes and the car to the shop and they are estimating about $1500.00 worth of work and parts....the major things he said he needs to be replaced rod in sterring wheel, throttle body assembly, and speed spensor in the transmission. I am being told by some it is not worth it to put $1500 into the car because it is going to be nothing but problems from here on out. Others are saying, do the work yourself or have the hubby do it. I honestly have no desire to attempt any work on the car and depending on the level of work I am not sure the hubby could do it either. How long do Cobalts normally last, can i get another 50K out of this car? Or should I save my money for a down payment on a newer car? Please Help!
