hello ptk675, i chose the vvti based from the following preferences:
1. My old toyota lite ace is gas as well. Mas at easy na me sa gas.
2. i love quiter engine kasi ayaw ng lola ko ng maingay kasi sila maingay din pag nag kwentuhan sa loob .
3. as i understand, mas cheaper ang maintenance after quite sometime.
4. mas mura ang vvti hehe
5. since day 1, gas is my preference talga.
6. and lastly, hindi ako ntatakot sa gasoline prices kasi lazy driver ako;tipid-takbo na driver, kahit tricycle pina oovertake ko lolzz...
to conclude it all, its just a matter of your preference and choice.. as i understand also, the d4d issue has been addressed already by toyota..
goodluck sa decision mo later.. tell us what did you choose...
