What HTK+ (O) to HTX costs on the road
What you pay for this step depends on where you register it: ₹78,000 to ₹89,903 on the road, against the ₹75,000 the price list shows.
Why the road figure moves, and by how much
Road tax is charged on what the car costs, so moving up a trim moves the tax up with it. The ₹75,000 is the distance between two price tags; the road figures add the tax and the charges that difference attracts.
The rate is your state's to choose, and they do not choose alike, so this one step is worth ₹11,903 more in one place than in another. Of the 25 states we can price this step in, Arunachal Pradesh comes out lowest, and Karnataka comes out highest.
Only the rate where the car is registered applies to you, so hold a dealer's quote against your own state's figure rather than the range. The range is still worth knowing: it is why two owners can quote this step to each other, differ by ₹11,903, and both be right.
