On fitting CNG kit, there won't be any change in the maintenance cost of the car but just ask the Skoda people for yourself whether this conversion will be compatible with the car or not, for that open the following link http://skoda-auto.co.in/query.htm . You need to get this job done from skilled personal as many are not aware of the technicalities of the car you have.
You are getting the car at a very good price infact its price should be a lakh higher than this, go for it but do check out the details why is this being sold at a low price. Check out thoroughly the whole body from outside, underbody and interiors. If possible, get it checked by a mechanic.
I am planning to buy Octavia elegance- Elegance feb/2003 model at 3.5 lacs with good condition from 3 owner (i will be the 4th). However due to its average of 10-12 km/litre, I am also planning to get CNG fitted. Please advice:
1.) if this getting CNG is right thing to do on this car as I want low running cost and I drive approx 60 KM/ day.
2.) Is the price at which I am getting the car is okay?
