Amaze is a compact sedan, and IMHO Honda designers have done a great job with the exterior design within their 4m constraints. But, the interiors have not changed when the segment moved up from a hatchback to a (compact) sedan, no automatic climate control yet. Also, Honda charges quite a premium for just the addition of a boot to the Brio. The points in favour of Amaze is the excellent engine and transmission. If one is looking for this, then Amaze is the car, especially if Diesel. Just my thought...
But if I am on the lookout for a hatch AT, and the Brio does not totally please, then VW POLO TSI seems to be a better buy. Its fun to drive and technically up-to-date in its segment. What holds back is the VW service rates.
The A-Star seems the best VFM and closer competition to Brio in terms of price vs features. It addtionally has split rear seats to make up for the small boot space. It misses the alloys but this can be fit outside. Defogger is missing etc etc. But the biggest down for me is the safety feature w.r.t. Airbags. How I wish Maruti got their ATs in their Zxi trim too. They seem to fail to understand that an AT buyer may not be totally cost conscious, and may pay up for additional features. Atleast for their scale, they can afford the logistics to have AT in both Vxi and Zxi trim and let the customers decide (just like Hyundai i10 AT)
Am actually keen on the Micra CVT and deferred the decision till Micra CVT launched. Its such a totally loaded car, ticks all needed gizmos. But, if the power and the ground clearance are questionable, it raises doubts on the decision making...
