If you ask me, I would rule out Ikon (making an excellent car is one thing, providing an 'acceptable' A.S.S with 'reasonably priced spares' is another ball game together. The Americans never listen, do they? Its for this reason many Head over heart thinkers like me stay away from it. I was sold over by the Fiesta, thanks to Ford's reputation, i striked it off).
Hyuandi Accent, excellent car by all means, provided what the Ikon failed to provide. Yet, the lack of diesel option and a ten year old model will induce second thoughts in the mind.
Logan- after the initial hoopla, sales are dwindling. Also the collaboration between Mahindra-Renault seems to be dicey. Definitely don't want to be one of those Dawood customers. Running a car whose spares are as scarce as water in a desert.
Battle Royale is between the Dzire and Manza.
If Tata had a better A.S.S with its quality issues sorted out, I definitely would have picked it over the Dzire. The rear seat puts few of the C and D segments to shame.
Based upon the current scenario I would stick to Dzire.
