Although the Accent 1.6AT doesn't share the minor woes that the 1.6MT CRDi has, and although it has features to be wanted, I would suggest against it because you're planning to keep the car for more than a decade.

I'm not saying that Hyundai isn't tested reliable throughout the years, because believe me it has been -- with the old Starexes, it's just that the Accent has a modern turbo and it breaking down is the last thing you'll ever want. Plus, you live in Baguio, replacement parts and what not might not be as abundant there as it is here. And the quality of fuel might be bad, that could shorten the life span of your turbo. Again, it's the last thing you'll ever want breaking down.

Same goes with the Elantra. I'm not really confident on saying that it would last, headache-free, for 15 years.

Unless you plan to expand your family to seven or eight, or would haul five or more people on a regular basis, there's really no point on getting the Innova or the Avanza unless of course, you like having extra seats that might come in handy.

Thus, it would be a toss up between the Lancer EX and the Toyota Altis. I would prefer the latter though, although the former seems to be more... good-looking, since I've tested Toyota's long term reliability with my previous car.

If ever you would choose the Innova, I'd say get the gas variant. It's much cheaper anyway, most likely has cheaper PMS cost, too. And really, it might be safer since clean diesel doesn't become available always. ;)

Goodluck!
