Ive got a 2015 mirage es, and have just changed the maf sensor, and pcv valve. Looking to do the O2 sensors next but I'm seeing prices of around $300 each online. This is just absurd. Furthermore, I found a pcv valve online for $30 but at all the local parts stores the prices were $100-$200. What is going on with the parts for this vehicle? How did a cheap car end up with such a problem as this? There are a lot of these cars on the road, so I'm fairly sure parts should be easy to get.
