I would suggest Wagon R for its affordable price for the capacity of the engine compared to the cars in the same range.Space-beyond arguable comfort in that price range.
I am very much satisfied.Only draw back I found is non availability of colors compared to the peers in that range. If any one want to get a car between 3 & 4 with better performance and less or cheap maintenance at current market can directly go for Wagon R.There should be some more changes required to differentiate a LXi and VXi which is now a very thin line and many would go for LXi compared to VXi.
