Q. I have plan to buy seven seater car in 12 lakh budget. Which one is better Honda BRV or Ertiga,( economically, laxurious, comfortability)

There is no reason for Ertiga to be compared with Honda BR-V. Honda BR-V scores much higher than Ertiga on all aspects like safety, comfort, space, fuel efficiency and reliability. I have driven Ertiga for 10 days at length in Kerala and have been owning a BR-V for past three years and my experience remains extremely positive for BR-V.BR-V offers great space (you can keep two medium baggage strollers along with a couple of bags even with their row seats open. The seating is quite comfortable, and roof mounted rear AC helps in cooling off the rear passengers easily. There is no body roll (like a high roof SUV e.g. Scorpio, Fortuner etc) on highways or hill roads and comfort matches any midsize sedan like City, Verna or Vento. Fuel efficiency for Diesel (one I'm having) is very satisfactory with 16-18 kmpl in city and 20+ on highway.

For your budget you can't afford brv's top trim which have more features but under 12 lacs you might get a perfect variant in ertiga and ertiga is comfortable, economical and looks good as well and has more space than brv only thing brv has better than ertiga is the engines other than that ertiga is a better family car

I have to agree with Mr saurabh he is absolutely right and if you want more performance you can opt for 1.5 vtec petrol engine which is marvelous
