That was probably me, or more likely my wife. Our car is dark gray.
We used to use Autolarte in Rionegro and were very happy with them. However, our regular tech left and the quality of the service deteriorated a bit. It was still OK, but not the superior care we were used to. The good news is that we just found out that "our" tech opened his own shop in La Ceja. He says that he still has a good relationship with Autolarte and access to all the necessary tools and manuals. We will be using him for all our non-warranty service. If you are interested in his contact info, PM me.
