Nothing wrong with old technology a lot of the time - less complex, less to go wrong and longer lasting. I'd have no problem whatsoever with one of those "old technology" Honda petrol engines.
As for the much-criticised Fortuner with its outdated pick-up chassis - our 2.8 TRD Sport has done over 160,000km in the three and a half years we've had it so far. I'm surprised how well it handles, no issues with grip, and it is as tough as nails, feels indestructible. Perfect for Thai roads. Ride quality isn't great over rough surfaces, but neither was it on my BMW 5 series on UK roads. The Legender has a lot of newer tech on it than the 3 year old Fortuner, not a bad idea at all to buy the current Legender ahead of the launch of the new model next year.
