Diesel car to run as a taxi

I want to invest in a diesel car to get into the tourist taxi business. My running will be limited to the city
and my budget is not more than Rs 5 lakh. What would you suggest?
Feroz, Mumbai

AAA Try and get hold of a second-hand Etios diesel for that money. It has a big boot, low running costs thanks to an economical diesel engine, and a spacious cabin. Just what you need to get into the lucrative taxi market.
