I should also re-state that for Bomber's sake, and using auto Hiluxes as the comparison:
Choice of:
A 202 M20 UC Torana hatchback OR
A Starfire MC6 Sunbird hatchback.
Sunbird costs more to buy and more to service, and if engine has a problem it costs a bomb to fix. Secondhand the price differential is huge.
Other qualifications:
You know 99% of engine problems with these cars are with the 4cyl.
4cyl gearbox is known to be p!ssweak
4cyl engine is made in Thailand, 202 is Aussie made. Same with boxes. (D4D Hilux and 4spd auto is Thai, V6 and 5spd auto is Japanese).
THanks for that clarification mate, your first one didnt make much sense 
New D4D's have the jap 5 speed to, incase you didnt know.
Still like my V6 petty though!!!
Judge, I dont mind old school diesles, pre common rail, but they irritate me during the daily commute.
Your right one of them wouldnt cost much more to fix than the average petty with a problem.
New Common rails are prone to injector failure, Pretty sure Toyota is around $800 an injector, and each injector has a chip that is coded to the car, so you need to have them fitted by a dealer so they can reflash the computer to suilt the new injectors. Also fuel rails are a single use item, etc etc etc.
A mate has a 06 3lt hilux which has a missfire, its definitely injectors, was quoted $4600 by Toyota to fix it.....Thats a frOcking lot of extra fuel that my 05 V6 chews before that money is payed off and they even up again.....Whats an injector clean and reflow for a EFI petty, like $25 an injector?
I did the sums when i was looking to upgrade from the '90 TD 80 series, and worked out with the average 8k more to buy a 3lt diesel Hilux over a 4lt V6 petty with my average yearly kilometers traveled and an average fuel consumption for both cars, plus the little bit extra rego here for a 6 compared to a 4, it would still take 8 years for the Diesel to actually start saving me money, PROVIDING nothing went wrong with it......
Cheers.
