Many many congratz sir ji :))
And it always feels great to have a Honda n tht too brandnew MA SHA ALLAH
The best part about this current city is the new titan interior I really love the new interior , just had some parking issues otherwise would have gone for base variant city in habenaro red as a DD instead of swift
