Hi All I m planing to buy second hand Maruti VERSA dx2

Hi All,

I'm planing to buy second hand Maruti VERSA dx2 for my own use. The usage may be less but surely not high everyday. But that's not a matter. My doubt is
1. Is it worth buying versa now
2. If I put CNG OR LPG kit, then anything problem with engine or any cost of maintainece?
3. How much I can afford for latest model versa?
4. How about the maintainence charges with this maruti model/

PLEASE HELP ME BY GIVING PROPER SUGGESSTIONS TO ME QUICKLY.
