First of all these are not 'few'. Honda Atlas total annual car sales is just around 25,000 units (out of which majority is 'City' Sales and remaining is 'Civic'). If they sell lets say 20,000 new Civics in a year, even that would stretch their existing production capacity.
Secondly, if the target market is happily booking without concerning for price, won't that give incentive for Atlas to keep a higher price? Consider the other scenario - if the new Civic launch was a disaster and consumers largely avoided booking without knowing the price, what would Atlas have done? They then HAD to introduce the new model then at reasonable prices - at least initially for the first year. But now it looks like they can keep a high price from the very start and throughout 3-5 years.
It's all about acceptability of a price above 28 lacs for Civic. If Honda gets 20,000 potential customers every year who can buy their new Civic and do not mind paying a price above 28 lacs, that's all they want. If the product is such a hit already, why bother to keep a lower price to generate even more demand, when they cannot produce 50,000 units for instance in a year due to capacity constraints at their plant. With this kind of response (that will also generate a highly positive word of mouth and a rate race among others), it seems that the potential customers Atlas require (keeping in view capacity constraints) will accept a price above 28 lacs for new Civic.
