Pardon my "English" .. but thats why I added "approx base price".If not already covered by someone else, what you said is incorrect.
42k is the official approx AVERAGE SELLING PRICE, not base price, which is 35k.
base is 35K, but the approx selling price will be 42K .. heard it from the horses mouth itself
.. and you are right, average is better than approx to convey the true meaning here.
