See, XLI already has a great resale, but Altis doesn't. But since you're looking for a second hand Altis, and thatg too a 3 years old, then you don't need to worry about resale, cause the term resale usually apply to 0 meter cars.
Now either go for XLI, or Altis. Resale wouldn't bother you either way. And what to choose, that entirely depends upon you, no Pakwheeler can help you on that.
If i were you, i'd have gone for new Corolla.
