Toyota Previa 2.0 D4D Review

2 years further on from 1st opinion, 100k & Toyota Previa is 7 years old now. Sticky rear door eventually fell off runner-after Toyota dealership "fixed it" with another shot WD40. Other rear door now going same way. £250 each side to get a door that works. Front discs again need replacing-£300. Air-con leaking from rear-up to £800 to sort. Best of all, front drive shafts apparently need replaced-£1300, but they,ll do it for £1100! Regularly serviced, not abused. Savanna referred to in previous review had 127k and 9 years old when we disposed of it & was still running around 5 years later, with no major mechanical failure. I don't buy into Toyota's vaunted reliability and this car is becoming uneconomic to keep on road.
