Every thing has its own advantages and disadvantages . maruti suzuki alto 800 also have various advantages and disadvantages too.according to me it is a very cheap in price and has cng facility also which we get in a car of price RS500000 INR and in thos car we get .it in RS300000 INR . Its disadvantage it that it has a very small engine which is of 800cc and is not good with cng . cng makes a engine weak and 800cc engine will become slow after installation of cng.
