They have a long history of increasing when rupee depreciates and holding the price when rupee appreciates.
In last gov dollar cycles, this exact thing always happened and if after a cycle dollar again went back to its old value, prices again increased even though dollar was same as its old value. That's how car prices have gone up a lot more than they should've according to rupee depreciation and also localisation has increased which should've actually reduced the effects of dollar. Considering localisation we should've always gotten a less than 100% hit according to rupee value but we got a lot more than 100% hit.
Now it really depends on car sales, LCs and CKD kits. Car sales are definitely dropping, which didn't use to be the case before, increasing the pressure on the companies but if LCs and CKD kit import situation isn't resolved, by September most companies are expected to almost completely deplete their CKD inventory and in that case due to shortage, even a base model civic going for 10million isn't farfetched, even if dollar goes down to below 200.
