Taller mecanico nascar - 57000 Nezahualcóyotl

I took my car in for one particular problem, the engine was making a purring noise. They disassembled the engine, opened it, cleaned it, changed parts and a few days later they did the same thing again. I paid a good wool, but it didn't stay. Then they changed the engine mounts (rubber bands) and that was it, for this second service I paid very little. After they messed with the engine, it went bad, it was throwing out a lot of white smoke and everything smelled like smoke inside. To fix it, he needed to pay another 4 thousand pesos, but now he had left, according to them. When they disassembled the engine, they got their hands on the exhaust pipe, I guess to disconnect it from the engine. Then it started making a noise like a rattle, they checked it and told me to take it with the muffler. I took it with the muffler and there, in my presence, without moving from the place and at all times seeing what it was doing, it showed me that it needed the catalyst. So I went back to this mechanic and they assured me that I hadn't brought it from the beginning. Since I had no proof, I couldn't prove it was them; however, in a previous maintenance and in another place, I saw that it did have it, because they lifted the car to change the ball joints. Returning to the topic, the rear suspensions were also changed, but after a month, it started to thunder again. I left a lot of wool there, for services of dubious quality. I leave these experiences for you to draw your conclusions and determine whether or not you want to take your cars there.
