Terrible. I bought a used car from them three years ago. Once the deal was done, I was persona non grata. Service is slow and inconsiderate. All the good service representatives have left. My last visit they tried to hose me for over five thousand dollars of repairs to my car that it didn't actually need. To add insult to injury, the expensive auto butler service that I bought with the car was done before my minor scheduled repair so there were grimy fingerprints all over the hood of the car. The promise to top off all your fluids is also a lie because I ran out of washer fluid the next day. I will never return to Cochran. If I need dealer repair, I'll find another GM dealer. And in a year when I'm ready to buy another car, it will definitely be elsewhere.
