I recently broke the thread off of my spark plugs in my 03 Mitsubishi Eclipse V6 3.0L I called around and everyone was talking 500-600 to just drill the thread out and put a new spark plug in. My grandma called RPM Automotive located in Ortega and they had one of the cheapest quotes in town. They told me to bring the car in and they would look at the car and see what they could do , less than 24 hours later they called and gave a price almost 200$ less than anyone in town. They ended up working on my car and finishing it the same day. I received wonderful customer service from the guys up front and they called a few days later to check on how the car was running. I would definitely recommend RPM Automotive to anyone looking to get their car worked on. By far one of the best places in town. I will definitely be returning and will never go anywhere else for work on my car. in the end they ended up drilling the thread out placing a new spark plug in and replacing the valve cover...BY FAR ONE OF THE BEST EXPERIENCES DEALING WITH REPAIRING MY CAR!!!!!!!!!!!
