From experience I always carry tools. I had a water pump go out on a BMW X5 last summer and not one mechanic in W Texas would touch it!. Me and a roughneck ended up changing it on a drilling location in the dirt, heat and wind. Youtube said it would be a 3.5 hr job and thanks to this kid not have big hands we were able to complete the job in 2 hrs. They wont change the oil on a foreign car in Snyder Tx. The big surprised was that no one in Abilene Tx would touch it.
