Karachi's car market is very different as compared to Islamabad's, Lahore's and Peshawar's car market. No one buy's a '06 model anymore because you can get a freshly cleared '07 facelift model in the same price.
I don't wanna argue with you but seriously you won't get good offer's with that price, try lowering the price to a certain extend, give an ad in the newspaper if you have too. You've been trying to sell this car for almost six month's now but it doesn't sell, why? Your price is what scare's the buyer.
A clean '06 Vitz '08-'09 Registration number, Same color, Tv/Navigation, With alloy's in the same condition would cost you no more than 950,000 here. So, before going koo-koo please think before writing.
P.S: As far as the accessories are concerned, the after-market stuff you have like the Backup camera, Security system and alloy's. They don't count when you sell a car.
