For several years I have take vehicles to Joan Guart's garage. He has just moved to new premises with all new equipment, just off the N340 near Camarles (Polygon Venta Nova, Avenir Glen Giner, 53  ) which is next to the padel courts on the industrial estate.
The workshop is GPMotor, tel 977 470 527 and email taller@gpmotor.cat
Joan speaks little English but has made a real effort to understand my limited Spanish, including sorting me out after another place had conned me. I wish him well.
