With your kind of usage, running costs will play an important role while making a decision. Consider the CNG variants of the Maruti Grand Vitara or Toyota Hyryder for their low running costs. Do keep in mind that CNG vehicles do come with their shortcomings, like limited boot space, and you will have to contend with long lines at the pump to refill CNG.
Another option you could consider is the Kia Syros diesel-manual, which will be a frugal alternative to the CNG options.
