Mga Sirs, I have an update na about my case.

I filed a complaint to DTI and I was given the dates of the mediation. At the schedule first mediation, the car dealer didn't show up. Representative from DTI then told me that they would inform the dealer to appear on the second mediation. They still didn't, but I was able to talk to their president after the DTI rep contacted the dealer's office on that day of the second mediation.

The dealer said that we could have talked about this and that I should not have brought this case to the DTI. I told him that they did not give me any choice since they did not cooperate the first time I called them and informed them about the mileage issue.
So anyway, after much deliberation at their end, they gave me 2 options: full refund minus the depreciation for the 4 months I was using the car OR they can swap my Civic with either Mazda 3 2005, 1.6 A/T or Toyota Vios 2007 1.5G A/T. I think the second option is much feasible for me so that I wouldn't really lose that much money (I will not have to shell out any cash even if these 2 are more expensive than the Civic), plus I'm getting a newer car compared to the one I got.
The question now is, which do you think should I take? Mazda 3 2005 1.6 A/T or Toyota Vios 2007 1.5G A/T?

Thanks for the help, guys!
