Here's a comparison according to opinions on Vitz Fan Club:
1. 4-Cylinder engine, better for cng... is it true?
3. Mechanics available
4. Spare parts available
1. 3-Cylinder engine, not good for cng
2. New shape
3. Mechs not available (is this true?)
4. Spare parts not available (is this true?)
So, could anyone please confirm these findings? Would anyone like to add something?
