I have had 4 Hilux over 15yrs or so, one had 180,000 on it when I got it, I took it up to 240,000 never missed a beat. As jobs got better and I could afford it I got newer and better trucks, But not one gave me any problems at all.
Just for a change I got a nissan D40 and one month outside of guarantee it had problems pressure switch on common rail fault,£1200 later it was ok but never could trust it. I would just save yourself any problems and get the best Hilux you can as I've never heard of a bad one.
