I think FB 15 is best as i know. Primara is also good. But FB is currently using me too. thers no any faults. can use only spending petrol if you buy a good FB 15. See there is 3 classes in FB15.
1. Basic
2. EX Saloon
3. Super saloon
there are many options in super saloon. try to buy a manual drive car and you will save fuel coz it does 13-15kmpl no dout
