With a budget of 10 lakh you have a lot of option and since you have posted your question in Maruti Suzuki Ertiga we figure you are looking for 7 seater family car. Maruti Suzuki Ertiga is an MPV and being a Maruti car, the Ertiga has minimum maintenance cost.
If you can wait for couple of weeks we suggest you to have a look on Honda Mobilio too. Honda will launch its MPV Mobilio on July 24, 2014. Other decent buy includes Ford EcoSport, Renault Duster in compact SUVs and Honda City, Ford Fiesta and Nissan Sunny in saloon segment.
Maruti has announced offers on Wagon R, Alto 800 and K10, but there are no announcements about offers on Ertiga. But, you can expect to get some offers later in the month. For exclusive offers, please visit your nearest Maruti dealer to find out the details.
