I bought 2 cars from Echo Park in June and have had nothing but problems with them both. I own 4 cars in total and have owned over 20 cars in my lifetime. I also come from the automotive background. I am not sure of the inspections they perform or where the cars come from that both of the cars would have spent over 6 days in the shop each in less than 3 months. I received another call from my daughter today that her car was headed back into the shop. We have had transmission problems, multiple sensor issues, and repairs costing hundreds of dollars on cars that have less than 40k miles and 2016 and 2018.
