Bottomline for me, engines are designed for the intended purpose, so one is not inherently tougher just because - diesel.
My 2c.
Rush wins hands down sa safety. If the TS intends to transport his family regularly at highway speeds (deducing from the 30k annually he expects to travel..i dont think city driving yan), then the added airbags are a boon. Kung mag.isa lang lagi, di issue ito since may driver airbag naman both vehicles. May abs ba ang base model mux? Wala ata iirc.
Both vehicles are built very similarly. Rwd. Independent front, solid rear axles. Coil suspension. High ground clearance. 7 seats. Etc. Major difference is the powerplant. The nr-series engine of the rush is no slouch naman kung tibay lang. Timing chain na din naman. The rz4e is heavily dependent on the turbo, and the higher pressures and temps mentioned above takes its toll in the long run. Spark plugs are definitely more cheaper than injectors if they need replacing. The simpler gas engine would be easier to maintain a decade or more down the line imho.
Power to weight, it favors the rush. 104ps. 136nm. 1150 kg...yung mux 150ps. 350nm. 2650kg. That's more than double the weight, but with only 40+ps more. Diesel has, of course, more pull. And since you have to rev the gas engine to get the power, it feels more 'anemic' despite probably very close acceleration numbers. When fully loaded though, the rush would certainly 'feel' it more since the added 300-400kg is 1)already 1/3 of its weight and 2)lower torque. If personal car (hindi naman siguri to school bus or uv express na 7 pax all the time), di major factor yan. Otherwise, wise option ang mux kung loaded lagi because of the extra torque.
Then the elephant in the room, cost. 300k outright difference. If he chooses to finance it, roughly the same difference. One kind tsikiteer computed for us na break even siguro more or less 3-5yrs assuming the TS didn't overestimate his 20-30k annual kms. Less mileage favors the rush. More use favors the diesel mux.
