Cars Q&A

Hi all. Looking for a quick car that is suited to hilly terrain (shimla). Budget between 5 to 8 lakhs (can go upto 10 if we get a great car for two more lakhs) 1. what all features do we check while buying car for hills? 2. Is petrol better or diesel? 3. Skoda Fabia, etios Liva, i20, swift dzire are some of the options we are considering.. which is better of all and please share if something is better than these all.. (dont like i10 at all)
