I have a '06 Belta myself, bought it in mid 2007. When there were quite few of them throughout the country, it hasn't bothered me at all till now mashAllah. Maintain it properly and it'll last you a lifetime. JDM vehicles are totally worth buying as compared to PDM vehicles. JDM vehicles have a quality of there own which cannot be underestimated and are worth every penny you spend on them.
The Toyota Belta comes in the following varients:
- 1.0L X
- 1.0L S
- 1.3L X
- 1.3L X 4WD
- 1.3L G
The prices start from 12lacs for a '05-'06 1.0L X and go all the way till 18lacs for a brand new '11 1.3L G.
The 1.0L (1KR-FE), 1.3L (2SZ-FE) and the 1.3L (2NZ-FE) are all economical engines especially the 1KR-FE, if I were you I would not get a Belta converted to CNG.
