brother no offence but once a car get smashed from the front even if was not such a major accident ,but at the end of the day u have repainted the booned ,so u must not expect some very good price ,as even if u put urself in a buyers list we people r reluctant to buy cars damaged from the front or even repainted as reselling issues come up,so if u want to get rid of your vehicle purely due to repaint issue that sell it at a reasonable offer ,as u can make choices in your demand once car has a blunt history butin this case u will be pushed agianst a wall while negotiating with a potential buyer as when some one puts money at stake they dig out things before finalizing things ,secondly if it goes for 550,000 i guess it will be a good catch as you have mentioned u own this car for two long years so u have enjoyed its peak ride and secondly u must go in a loss as 2 years back it must have cost you either the same price or a bit more,cars r on fire these days in terms of prices but were engoying quite stable prices a year back speically in case of baleno
