i bought a 2006 vitz and converted it on cng with the best landi renzo kit in the market with the lambada oxygen sensor, but i soon realised that the new vitz cannot be run on cng due to its CVT auto transmission. just like in the city vario. so i had to take the kit off. i still have it. its been used for a month or so only. if ur interested in buying it let me know.
