What are your requirements, your budget, your usage?
I had booked a petrol Amaze the first time I saw it, but then cancelled it. First is that Honda is giving the worst interiors in its cars. I sat on the back seat, and believe me, I felt like I was sitting in a decade old used car. The interiors are totally crap, never imagined this from a brand like Honda. I think this is due to Honda's new approach. Before some years, when Honda was producing better cars, they had all cars above 10 lakhs. And now all cars are below 10 lakhs, the CR-V being the only car above 15lakhs. They just want to increase the volume. Dont go blindly towards the mileage that they quote. And do refer the bonnet strength, the materials used. Great mileage usually means inferior part quality. And other weird thing, which ultimately led me to cancel the amaze was the absence of proper space to put speakers. The tray given in the rear cant hold speakers greater than 4 inch. This means I am forced to hear sound from such small speakers for eternity. Ofcourse you can cut the tray, but that would deteriorate the look of the interiors.
I think out of the two options, I would prefer the swift dzire.
