Suzuki law
prices prevailing on Delivery wud be charged, in case of diferent Cities, at the cost which the car leaves the factory gates is charged, u can claim it, by checking the dates, if they are officialy reduced, or the showroom people agreed to give it under cost
same thing happened wid a friend Honda City price increased and the dealer (KHI) demanded more, but they inquired that the car had left the company (lhr) before increase so old price was paid
