I worked as a mechanic at a Nissan dealer and they had problems you would never see on Toyotas or Hondas. A lot of which was related to cheap thin wiring and bad connectors. Maybe they are better now, but I see no reason to buy one, when Toyotas have always served me well.
I'm going to drive my 2001 Tacoma with 180,000 miles on it until the wheels fall off. Or my wheels fall off, whichever comes first.
Most Toyotas that come in my shop now with very high miles have no leaks and the owners say they have never had any problems. But there are a few exceptions.
