My son has an old Toyota 4 Runner 2000; it started to shake and vibrate at about 60 MPH, also had a metal noise when breaking or accelerating. Enrique inspected the car, and determined that was something with the 'flecha' and 'crucetas', and that it was relatively common on this kind of cars. He gave me a plan of action that included two potential paths, depending on the findings of the actual disassembly of the parts. The diagnosis was accurate, the problem was solved, and the price was as agreed. And for the metal noise, he indicated that was a broken pipe on the exhaustion system, recommended me to take the car to one of his friends, and for $20.00 he fixed the muffler. Thanks Enrique, and thanks Pepe.
